The main dev told me himself that he abandoned this project well over a year ago (via the main discord)

It appears some great patrons have donated their time to update this so it would work with newer versions of MC, but unfortunately it causes much more lag than it helps.

For example, I use Dynamap and when LagAssist runs, it jumps my RAM by 60% and my CPU by 90% out the box and Dynamap cannot run without crashing the server. Removing LagAssist and bringing back Dynamap, my server sits at 8% CPU and no more than 33% RAM

Won't be using again. Not worth your money.

Maybe if the developer comes back and updates it and fixes it up (unlikely) then I'll change my review.

No hate to the great people who tried updating it, it's folks like you that developers need.

Most lag assist plugins (including this one) are not worth it, they often consume more performance than they save you.

To truly reduce lag you need to properly profile your server to find the causes, optimize your server config, remove laggy plugins (or ask the author to fix the lag) and get better hardware.

UPDATEEE PLEAASEE UPDATEEE PLEAASEE UPDATEEE PLEAASEE UPDATEEE PLEAASEE UPDATEEE PLEAASEE

Unfortunately this plugin is no longer being updated by the original developer, seriously, it's hard to even contact the guy on discord. You all can find an updated version of LagAssist where it is being updated by alivn: https://github.com/alvindimas05/LagAssist.

This has versions for up to 1.21 as I recall. If you are trying to get refunds, there is nothing that the Admins on the discord can do except ping Stef and pray that they answer.

add 1.21 support... this is useless on newest versions. a lot of errors are showing

Plugin doesn't support Java 21, which is required after Minecraft 1.20.5.
Will update review when the plugin is updated

Dead Plugin? We've reached 1.21 and there are no updates yet............................

No 1.20.4 Support!

Version 2.30.0 requires Java 17 or higher to work. In other words, it will not work with minecraft versions earlier than 1.17.

Will update rating when dev updates to 1.20.4... great plugin but devs interests are clearly elsewhere and this plugin will likely not receive much more (if any support or development).

dead plugin and the dev looks like they moved onto a different project. don't expect any fast updates or any at this point

Unfortunately, poor support as far as statements about new versions are concerned. Is the plugin still active at all?

its fine, nothing too special tbh
.........................................................................

Great plugin! I always use it every time I run a server. Though that alone is rare.

Great customer support! They answer your questions quickly in the Discord, and I was able to get a full refund when I noticed the plugin not working well with Geyser.

Aside from the issue with Geyser, it's a great plugin! It has useful features that are fully configurable. You can choose to disable the features you don't want on your server easily.

The only thing I didn't like was that there's only one permission node that gives you access to all the commands, excluding the client optimizer and reloader.

Useful plugin, works well, gives a lot of control over the server and helps to cope with the load

This plugin is a life saver for server owners who often experience uneeven player rates and lag spikes. It causes a very slim amount of lagg, but that is worth it to say.

Awesome highly recommend creator is very kind, patient and helpful. And plugin helps a lot on server <3

Great plugin! we love this plugin to keep track of the lag on the server and what it causing it

Plugin works good and made by un baiat roman sexos. I use it in all my servers, very usefull

Please ignore the bad reviews below.
This is honestly the best most conclusive antilag solution I have ever used. It's efficient, and does not cause lag. all modules are incredibly useful, and it even allows players to optimise their own game client with /optimize
clearly better than clearlagg

five stars from me ⚝⚝⚝⚝⚝

I had tried this plugin thinking it would be a good idea, but not its functions as blacklist by world does not work autoinitialize the modules without one not ask them, some functions are unnecessary for one and can not disable it, I told him my problem in a ticket and took more than 20 DAYS, THAT WITH TODAY WE ARE GOING TO 30, The creator mocks in the face of one.
PROOF:

I thought he would be busy but he was several days talking on his discord server convincing others to buy his product while leaving others out. just pathetic.

This plugin is god awful! I bought it for my 1.16 server and it didn't work properly. I joined their Discord and asked why features did not work and tried to get help, but was ignored. Now that 1.17.1 is out, I thought I would try and see if it would work better, but it has actually gotten worse. Now no matter what I try and change, players can no longer remove items from their inventories and the chunk analyzer gives me random chunks every time I use it and the teleport to chunk just plain out does not work. I asked for a refund after 4 days of owning it and was ignored, and now I see a "One week No Questions Asked Refund" on the page. How come I was not allowed this? How come I was ignored on the Discord? I want my money back! Don't waste your time with this.

great plugin, was wondering what the item id of chunk hopper is (so i can make it craftable)

Make the server work harder

===================================================

Top 5 Favorite Plugins. For me, mandatory on a server. Can't wait for 1.17 release!

Didn't help anything Not wearing is still much better

============================================

Love this plugin. And Item frames with LaggAssist Monitor? HOLYYYYY I love it...little things man...little things...

Awesome plugin that allows to perform analysis and apply quick fix during ongoing random tps drops and easily find out where from they come
- one click lag machines finder/disabler
- automated actions based on configured tps drop thresholds
- pretty annotated configuration parameters (i was able to correctly configure it just by looking into config options comments)

Allowed us to identify and fix tps drops without wasting a lot of time, when adding more resources or server and configuration tuning didn't worked anymore

Definitely worth every cent, keep it up, cheers!

Excellent plugin, and very very fast support. If you think to buy other anti-lag plugin - don't think. That one is the best.

Does its job perfectly well. The docs can be a bit lacking and/or hard to decrypt so make sure you ask on discord in the clearest possible way you can, to try and see what settings relate to which feature.

Good plugin for analytical purposes. I found multiple lag machines by configuring it to pick up the main culprits so I could remove them and ban offenders. What is disappointing is the lack of a language file of any sort so I can't translate nor customize any of the messages except select few.

Excellent complement, my server went from being 14TPS to 20TPS. In addition, the support team is very attentive and helps you in everything possible so that you no longer have any lag and TPS drop.

help me please!

This plugin has helped me to get a lot of performance for the serverup! I would like to continue to recommend it :) [Use 1.16.4 Currently]

Running perfect on 1.16.4 semi-anarchy minecraft server. Before using this plugin I was stuck like "bro my tps is trash". But after using and configuring this plugin, it's lag free so far. I hope it always be like that.

My server IP is theminers.id

Seams okay so far. I run a skyblock server that was suffering huge tps drops from spawner farms. I'll have to see if this plugin makes much difference in the next week. It has great monitoring tools tho.

Really good plugin, really usefull ! I use it on my server and it really help to limit lag !

You can duplicate monsters with Nametag - &fWither_skeleton &cx100000000 .... its a bug?

Good plugin but It's has been 2 weeks since I bought the plugin and still can't use it because generates errors and laggs my server. Will give a 5star rating when solved.

The features are a bit barebones, but they are all excellent and works perfectly.

I love this plugin, easy to configure and you pick which features you want to use. There's only one buggy feature "pre-spawn-check" but I got support on the Discord within minutes. This plugin made my server impossible to crash! I had many players try all kinds of lag machines and hacks for months and no one was successful. I recommend pairing this with IllegalStack and Spartan for a bulletproof server!

Terrible Support, the author never respond, please dont waste your money! . .

Excellent plugin for my server, got so many features. Thanks for your great work on this plugin.

You can hardly get help because the author won't respond to you, and the plug-in is rarely updated. It's been months and no one has responded to me, in discord.

Great plugin except for this error.

I was prepared to talk shit about this plugin and that it's actually equally as good as react but if ANYTHING this plugin is better and having this plugin and react makes an almost uncrashable and lag free experience I've ever seen I have a vps from HeavyNode that has 10 gigs of ram and an i7 6700k with 3 vcores. I was flying at speed 10 backwards across my server didn't crash once with my testing and react being in low mem mode. The only setting I had changed was LagAssists chunk optimization feature which definitely helped. The whole time server was at 50-100% cpu usage and didn't crash. Fuck me sideways and call me impressed

This plugin deserves 5/5 for its SPIGOT PAGE. Great ad. Let me say I own React (which the dev is currently on break from) but the idea that this plugin is better than a functional React is laugh out loud funny. There is no comparison. The ad claims it is used on so many large servers - if that is true it is for it's mob stacking (which I did not use). This plugin has so few commands/functions compared to others I have tried - I do not believe it is worth 1/4 of the 11$ paid. And that is before getting to the discord for support. Asked question, waited about a day, with no reply, then asked if there is any support in there - and got a reply, saying to turn off that option. wow. BEWARE this plugin is horrible, and unless the mob stacking is incredible, should likely be removed from spigot. Unreal.

Amazing plugin, I am using this on my server and it's very easy to use and customer friendly. It does exactly what it should do, if you buy this make sure to read carefully through all functions. This due the fact of misconfigurating something can cause huge issues on your server, but if this happens it's probably something you did yourself. The support has also been good for the 2 years I've used this. I highly recommend you buying this. Also I want to thank the developer for having such a great plugin open to use for everyone who owns a server, keep up the great work!

A few weeks ago I gave a 3-star rating but the author still didn't fix my mistake! It's so frustrating about his way of working

Mob stacker is working very bad! :(
This is the only thing that I want this plugin to do for me and failed! :(
PM me on discord and I will show you what I mean!
Discord: ≪ᶻᵀˣ≫#0001

Es muy buen plugin en mi punto de vista, no lo compre como la solución mágica al lag de mi servidor si no, como una forma de ayudarme en disminuir y detectar los problemas que pueden crear retrato. si ustedes buscan una forma de reducir completamente el lag, no compren plugins si no jars (otra cosa es que valen como 30 o 60 veces mas que este plugin)

THIS PLUGIN IS WORST PLUGİN.
DONT BUY SAVE YOUR 10 USD.
DOEST NOT CORRECT IN ANY WAY.
I WANT REFUND THANK YOU

Not reccomended:

1) Dev answers very slowly, at least he answers tho
2) Many functionalities of the plugin are broken and i reported it multiple times without success
3) Plugin constantly outputs exceptions to console when server lags
4) Mobstacker never worked
5) Dynamic render distance never worked
6) Mob culler NEVER worked
7) Boat chunk entity limit NEVER worked

I give two stars because at least the dev answered to me some times, but very slowly. And because chunk entity limits kinda works.

I am sorry for this, because the dev is a single dude working on this. But that's what this plugin deserves in it's actual state.. nothing more. Ill change this review in better if he manages to fix all the issues!

Fantastic plugin with a variety of complex features. Well worth the money (and more in my opinion), definitely worth the buy.

Good but please fix the lag monitor map...................................................
Version 1.8 PaperSpigot

This plugin is completely broken on 1.8 - 1.8.9. Lag monitor broken, ping statistics are weird.

Could say that it's the best lag prevention plugin that exist in the market right now.

I give 4 stars because the plugin is the best one out there. I used to be getting TPS as low as 7. Now I don't see it below 19. HOWEVER, if you are looking for support with the plugin and need urgent fixes, I would not recommend as there is almost 0 support. This is a shame as the plugin is premium. My discord message has been sitting there for nearly a week without a response and this is about the 4th time

All in all the plugin is very good but it throws some errors
We are running it on a 1.14.4 paper server
For example this one:

Bought it 3 minutes ago - already in love with this plugin!
In such short amount of time I was able to localise and eradicate lag farms on my server (~50 Players)!

Beyond expectation,
5 Star Dev, 5 Star server, 5 Star Life,
5 Star for you for me and for all of us..

I dont know how to add lapis pls help ^^ .

Hope you can update the configuration of (Chinese), and (Chinese language), very good plug-ins, give you 5 stars of praise.

The plugin is very helpful and gives me the information I need to improve the server!
I don't let the plugin take action automatically, I just let it measure the performance and then I react manually if necessary.
The support on the Discord is also very good!

This is good plugin to optimization server.
This plugin have positive author/cheap prices/many features .
I use this plugin for 1 years,never have any issue.
Working very well at my askyblock server.

One of the best. I literally had a huge redstone clock from my friend on a private server and this plugin culled the wirings efficiently. Would recommend 11/10.

My testimony:

Hi, I own a Skyblock server that reaches 70 players online at the same time every day.

Or at least it came, before so many chunks loaded with tantls players online, redstone, run farms, spawners and all the challenges a skyblock can offer.
But this was being a drag because the lag was so large that several crashes occurred throughout the day because of low memory.
The TPS was reduced to 5-6 making the server impossible to play and have fun.
What's the first thing that comes in mind?
"I'm going to remove plugins as this will make the server lighter."
In fact this is a true statement, but unfortunately it did not reach what was to be expected.
It was then that I discovered the LagAssist plugin.
At first glance, before acquiring the plugin, I could not even imagine what it really is capable of doing.
I thought:
"But one more plugin will only worsen as it is one more plugin"
But that's not what happened.
Before buying I contacted support through discord and was quickly helped.
A truly amazing and fast support.
Then I got this plugin.
And everything changed.
With a large grid of configuration options this plugin allows you to faithfully adapt the qualities of your server, in addition to
The TPS of my server has stabilized again at 19 and since then we have not felt lag, players have already felt the difference with LagAssist, which now prevents my Skyblock server from starting the winery, making it fun again.

If you are reading this text, you have not yet bought the plugin, I can firmly state that this plugin will help you!
I highly recommend it.

You will not regret it as helped me, it will help you too!

And you can always count on the support!

~ My greetings ♥

Thank you very much. You much appreciated!
It's really great to see devs interested in developing lag-reducing plugins. #5135

Absolutely amazing plugin for managing lag! It's super light weight and is extremely configurable!

I've used both LagAssist and React and LagAssist uses less resources, and is more versatile at handling lag.

I swear this isn't a paid promotion this is seriously a great solution to server lag of many forms. 10/10

Thank you for the amazing plugin stefatorus

Great plugin. I have really helped us out a lot with our new SkyBlock server which runs 1.8.8. Does a flawless job and gives the players a great and lag-free enviroment.

The features such as redstoneculler and physics-disable have been a great help for us too. It have prevented a lot of crashes from players placing a lever and redstone around it in a large radius. Spamming this lever would crash the server, but with lagassist it breaks the redstone or disable redstone entirely until the server is back on track.

A lot of customizable values in the configuration, its a must have.

We tried react and other plugins, but as most of those plugins takes up more performance than they release. We can currently have about 20-25 players without dropping below 20* tps. Without LagAssist we would go below 20 tps after 10 players ish.

The plugin keeps our servers clean, protected from stupid people and the author is very responsive and a great person.

Amazing plugin and a very hard working developer who always updates the plugin. Whenever I needed him to help me with an issues he was very helpful and friendly. Well done mate

This plugin is packed full of features, the lagmap and benchmark are worth the price alone! Thank you for filling a void in Minecraft server management. Keep up the great work!

the entity block limiter per chunk doesn't work, this featur is very interesting if you can debug it pls do

Better GUI, easier configuration system. Thanks a lot and keep up the good work!

Good plugin, a few bugs here and there but the devloper is very active and tries to fix all bugs asap. If the plugin gets more custom messages and gui options then I would rate it 5/5 Stars. Currently you have to be happy with the GUI and message layout as they are very limited to be changed but since its a admin tool, its not such a deal breaker.

Very nice plugin!
I dont have problems with this plugin!
Thank you so much ! :D

Good plugin idea and function but there are so many bugs,
Such as players sometimes can place blocks in no permission residence
area and askyblock island areas but cannot destroy them,this problem bothered me a long time and drives me mad,I finnaly figured it out it was
caused by this plugin

That plugin is amazing like a pizza!
- That author is Smart like i9 procesors!
That plugin is a medic for your server.

The plugins is good but not %100 worth it.
pregenrating a world is not fully working, if you use it for Survival server it would break half the stuff.

I would rate it as 5 stars if you can improve the most useful features.

It's an excellent plugin.
It help me kill the server lag and optimize my server.
I like it!

Bugs.

Good support and quick fix, There is five stars for this plugin <3
============

Plugin works perfectly.
The author is very smart and the support is extremely fast.
Stef has helped me with many other things, thank you <3

Best anti-lag plugin out there, buy it!! the price should have been like 29 usd or higher. Amazing plugin

Update working on spigot 1.8 . <3

Excellent plugin.
I was looking for this for a very very long time and I finally found it. LagAssist it's a very useful resource and helped my server to run at 20 TPS everyday.
Also I would like to mention that the developer was very kind and explained me how to configure the plugin :)
Thank you very much. You much appreciated!

Not working this version on spigot 1.8 and allot error on console spam .

REALLY WORTH IT, I have used many of these plugins, and this is the only one that optimizes your server, it has a lot of interesting and useful systems and options. This is MUCH BETTER than react.

Amazing resource, detailed well on it's spigot page, well optimized in game and does exactly what it says. I would recommend this plugin to anyone who wants to monitor and improve their servers performance.

10/10 resource. Amazing developer constantly updates his resource.

Thanks you for plugin!

Amazing Plugin!

Good Plugin!!!

Nice Exellect Plugin. Nice!

Perfect plugin, i like how it blocks redstone machines.. its a amazing plugin !

Thanks you for plugin!

Amazing Plugin!

Do you have discord?

Nice Exellect Plugin.

Thanks a lot for this plugin this make's it way easier for me to check for lagg and to prevent lagg. You mentioned some big facts above so you know what you're talking about that's a good thing. Keep working on this amazing plugin! (I don't like the way the GUI looks)

Works as advertised on Paper 1.12.2. Good step-up from the likes of LagMeter and LagMonitor if you don''t mind paying a couple bucks.

Very nice plugin with a colorful GUI and colorful commands also is very nice at stopping lag machines on Survival; can you please add my server to Server using LagAssist? thank you.

Very usefull and nice plugin. I found all my laggy chunks :)
The author is very helpful and open for suggestions!

The plugin is very functional, I recommend. Hoping to see some additions in the future to look like other plugins (which I will not mention ^^)

High quality plug (and I'm picky)
Nice work Stefatorus. I'll let yo know when I get deeper but first impression after download is good
