Everything is very good except from the CustomIA option. Idk why, but that makes the server even more laggy than before... from 5800 ticks overloaded, with this plugin with all options enabled except Redstone and CustomIA, we went to 4900 ticks. Great work!

Good Plugin, i use it on my community CraftAttack12 Server with AMD Eypc Threads and works perfect IP: HeroAttack.de

I really like this plugin! The design is clean, and it integrates well with Spark. I understand why some users might experience issues on the first install—I had to make a couple of adjustments to get it working exactly how I wanted. Initially, I was puzzled by my mobs stopping movement, but it actually makes perfect sense: if they don’t need to move, they won’t. For players who prefer otherwise, the lagfixer menu offers a user-friendly GUI to adjust everything as desired.

The plugin also includes other useful improvements that I appreciate, all while keeping things simple and streamlined. It avoids unnecessary features that aren’t related to performance, maintaining a sleek and focused design.

Keep up the great work! I’m looking forward to future updates!

It's good to use. I want it to continue to be developed. very good thank you very much.

After installing the plugin, half of the mobs ai completely stopped working. It looks like the custom AI broke the server, and it doesn't help that all the lag fixer features are enabled by default, which resulted in player's farms to malfunction

The plugin works terrible. I had to restart server like 10 times in 3 hours because the plugin was crashing and was responsible for such a lags and no chunks rendering etc.

I added this plugin expecting a boost in my server’s performance, but it didn’t change a thing. My TPS remains low, and the server still lags, particularly during busy times.

I installed this plugin hoping it would improve my server's performance, but it didn't make any difference. My TPS is still low, and the server continues to lag, especially during peak hours. Completely disappointed!

Amazing plugin. We use It in all our servers Network. It only needs chunk unloading for being perfect ❤️

I downloaded it to my minecraft server and it was as smooth as my grandfather's ashes

I like your plugin, but could you help me make the text bold in the messages? thanks for the good plugin

Your plugin is very good, I hope you will soon update your own language file so that we can translate the language for my own country. Thank you for creating such a great plugin!

This is the best plugin for optimization! Set up configs in the core and install this plugin, enable the necessary functions and the server will live for a long time. My server is on 1.16.5 Paper with 60-70 plugins with 4 (2 self-written) anti-cheats, anti-xray, with LPX and multiworld, it can last a very long time, especially thanks to /lagfixer free. It also fixes lag machines such as on redstone and entity. I use 1 version older. I would really like to see FPSHelper, only without any errors in packages. I LOVE LagFixer!

removes sounds of mobs

--------------------------------------------------------

excellent plugin, it helped us remove quite a lot of lags and server crashes. <3

Loveyou <3 this plugin really good <3 <3 <3 <3 <3, i recommend this for big survival servers

So far this plugin has improved the TPS on my server. I appreciate the increase in how well my server is running. The gui menus dont seem to work as intended however.

it's a good plugin and it help me a lot! Anyway I suggest you push this plugin on modrinth :>

Please update to 1.16. As this version is very popular. I will be grateful.The plugin itself is good, very good. I especially liked that FPSHelper is coming out soon

Well my server has 12GB RAM but after using this plugin it feels like my server got more 10 Gb extra.. Good Plugin.. Recommended for aternos users

yea the title of this plugin didn't lie, 10/5 grab this for your server and your server will not lag

well this plugin causes lags on 70 players tps was 9 server hosted on I9 13900 CPU
when i unloaded that plugins tps was 20
so i don't recommend this plugin until dev fix

the plugins works very well!
The support on discord is very fast! Big thanks you for your work!

I Installed this plugin and have no regret. Developer is releasing a lot of updates quick. the plugin getting better and better. Thanks

As always, great resource!

I think ppl now only leave bad reviews just for nothing. That's sad. Hope this plugin keeps getting updates.

Ew ew ew ew ew ew ewwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww

This plugin really sucks it wont clear ANY drops im now using it as a auto broadcast plugin!

Hi I really like this plugin, but could you possibly add RGB support? Thank you!

I like a nice plugin, I just installed it, my expectations are quite high, I support you.

It's a very good server plugin, but it doesn't generate configuration files, which are blank!!

Great plugin for small servers, didn't try it with a custom server configuration, just the standard one, and works kinda well.

Randomly reloads chunks and uncaps the render distance for the player. I wouldn't recommend this plugin at all. This is NOT a lagfixer.

Very helpful plugin, it successfully solved the lag problem encountered by my server, thank you very much!

I have no help about feature Mob Stacking, it's break all Animals / Villager , all entities. It's same without this plugin after uninstall it. Please fix this and i edit my Rating...

it's not worth downloading because i was getting to many errors in the console so that why i gave it a one star

atleast create a back feature like this...
https://streamable.com/g3pm70

Very good plugin, it needs to be updated and some things fixed. But with this I want to encourage the author because it's really worth it!

The best lag fixer plugin i ever used, my server from 16-18 TPS now stable at 20 TPS :D
Thanks you so much developer :>

If you startup your server with this plugin, it says that your server is unoptimised BUT how glad you can buy a server optimisation from them.
After you open a ticket in discord, it says that the price for optimisation is 15-25$. This kind of business sounds very suspicious. I highly recommend staying away from such things.

Plugin works great after update 1.1.0, but the ItemsCleaner spams the chat like crazy, I don't know if we can, but would be nice to allow us to turn off some messages and leave only the 10 second one for example. It also doesn't support pages in the abyss so it deletes items too often.

I found this plugin a while ago but didn't think much of it, but I have noticed that you add so many features almost every day to this plugin, and one day it will be the best anti-lag plugin!

I really have nothing else to say! (Except that a few screenshots in this spigot page from ingame would be cool to have)

I also would like it if you'd add some of the features that a plugin called "Neo performance" has :D (Like server halting)

I've used this plugin before and it worked great, the only issue is this started happening with this update.

The worlds setting in this config doesn't seem to work, so isn't CustomAi enabled for the following worlds, but other worlds that are not on the list will also be affected. I'm a little confused.

Can you add a module to clean up garbage on the ground? I would like to make a superficial comment that you can consider

Please add Folia fork support! amazing plugin it works amazingly i recommended it to everyone

The developer is super active! Fixes everything just in seconds! Already love this plugin

The plugin is really cool! But can you add notifications for admin with placeholders and sign place like in AntiRedstoneClock please >.<

too good to be free.

I would recommend adding an option to reload the plugin and more optimization to config.yml

LagFixer is an amazing plugin! It has completely eliminated lag on my Minecraft server. Creatures move smoothly, and redstone no longer slows down the gameplay. It's a game-changer and an absolute must-have for any Minecraft server owner! I highly recommend it to everyone!
