this plugin helped me a lot on which plugins consume the most in my server. It also helped me detect memory leak!

Its a good plugin, however my spark profilers are not sending me a link or showing in any form of console or logs. I can not get help with this as there is no support server, rendering the plugin useless to me.

If you don't like this plugin, then something is seriously wrong with you, it's so much better than timings (or other crappy performance (draining) measuring plugins) for finding what's lagging your server and has very little performance impact, 10/10, best performance measuring mod/plugin.

Everything is fine but the placeholders are not working, I don't know if this is my problem or if someone else has the same problem.

My server was laggy before now its not good job

Good 100/100

Very good for other servers not laggy like other server

Works very well, usefull for nauwkeurige tps [which means accurate in dutch lol]

this helps my server a lot!!!! it decrease my server cpu load and ram!!! thank you so much^^

Ottimo plugin per chiunque abbia un cervello (e un server lol)
Lo consiglio vivamente, questo è uno strumento che ogni proprietario di server dovrebbe utilizzare.

Plugin command crashed with a java CompletionException and graph provide whatsoever no useful information.

Just realized that I don't think I ever left a review in spark and its one of my few must-use plugins. If you want to find the source of any kind of lag this is wonderful.

Also just great to test the performance of your plugins. 10/10

One of the most helpful plugins if you need to find a performance issue in your plugin. It is a great development aid :)

Great plugin, really helpful to identify issues causing lags. Highly recommended !

Great plugin for anyone with a brain (and a server lol)
Highly recommend, this is a tool that every server owner should be using.

horrible bad attitude support in their discord, works fine for obvious problems but you really dont need it unless you are a monkey

Mainly rating five stars to make up for the stupidity of the people below leaving lower ratings. Spark is amazing, and essential for diagnosing any kind of lag and monitoring performance for any minecraft server.

not shows all timings like default timings.
for example nantibot.
.........................

Great plugin for profiling the server, i use it on 1.19.3 paper
i'm not expert but i use these 2 commands

/spark profiler
and wait for 30min then
/spark profiler --stop

then the paste link shows me what plugins using the ram or cpu which is so cool

but felt bad for the review under mine, maybe you should check the support and try to improve it. i know though the ones who provide support can get stressed by the amount of people who ask for support without checking anything before asking.

I would've really liked to use this profiler, as it really helps you identify lag and other sources of problems. I am working as tech support and wanted to ask with professional knowledge about the cause of this problem. After reading the discord chat of their server I was shocked, though I tried to begin a normal and peaceful conversation - which quickly drifted into a rant about me 1. running the server as root 2. not posting the logs on mclo.gs and then ranting about me not noticing what I thought was a spelling error (I didnt consider it being a website, but the minecraft log files we talked about before) 3. ranting about the server being allocated 45GB, while the ideal max would be 16GB without caring about the server setup and 4. finally reading in the log it is an offline server and straightup telling me offline servers are not supported as offline minecraft is ILLEGAL (which is also not stated anywhere and offline servers are a key feature of minecraft and NOT ILLEGAL)

After that I still got talked down by another member on the discord stating our server concept is rubbish while not knowing/caring about the requirements. We serve minecraft to youths and education edition is NOT the solution here at all. It is completly different from normal JAVA and should not be treated like it. This was the most unpleasant chat I ever had on a discord server - and I have been on 40+ discord servers for the plugins we already have and plan to add, even the IntellectualSites support was WAY better and that is saying something.

I have A LOT of experience with handling minecraft servers in the wild and have seen many configurations over the years. Being talked down like that shouldnt happen with any support, even if you are the developer himself. I cant believe nobody else complained here after seeing the chats on discord - but maybe those reviews were just removed. A plugin with not a single rating lower than 3 seems really sus with it being so popular.

This is a fantastic plugin. I use this plugin on my server (Currently running 1.19.3), HalfastMC (its a UHC SMP) and the players there love it. Thanks for making this!

A must have
the perfect plugin to monitor performances of you server
<33333333333333333

Cheers.
It's nice that the background profiler doesn't need to be stopped to take a custom profile.

Definitely a must have, cat approved. Appreciate the work done here :3

Would be awesome to have a benchmark option

One of the best plugins on the site, and it’s open source. Love this plugin and developer!

Some could say it's Timings v3, the best profiler! The design of the web viewer also looks a lot more modern!

The best performance profiler ever!
You can see a lot of things like how many CPU, Disk, and RAM is server using or how many TPS is now and you can fix problems with this!
Love the author's work!

best profiler, good way to fix any performance problem and should likely replace timings entirely

An incredible app that is helpful for both server administrators to identify sources of lag and also developers to optimize their plugins.

Spark has such an intuitive visual layout and honestly, I don't know how I would do without this plugin.

Awesome dude!
This update will be awesome! Cheers

very nice plugin. Super duper helpful!!!!!!!!!!! Definitely get this!!!!!!!!!! UwU

11/10 - Absolutely the best, most useful piece of server software available today

Thank you for your work, great resource ! .

The web interface in spark has a number of improvements over the standard WarmRoast one, in particular the ability to apply MCP mappings directly in the interface, without having to go and obtain+configure the mappings yourself. :)

Been using spark for many many years. As a developer it is a great tool to find and fix bottlenecks, tick stutters and even to diagnose plugins server admins created themselves. While timings give people hints of something being wrong, spark answers what.

Excellent plugin, essential to any vanilla or modded server. My most used features are the healthreport, tickmonitor and profiler.

Awesome new viewer changes
Thanks

What an amazing profiler. Extremely easy to user and provides all the information you could ever possibly need to make your plugin more performant! I would appreciate a feature to automatically filter out sleep functions in the numbers, however.

Honestly one of if not the best profiling plugin available. Spark has been super helpful finding memory issues on my server network. It also works on bungeecord and is very helpful for finding issues that are limited to the proxy.

Great for profiling plugins, especially if you develop your own and want to check for performance problems.

Amazing update, thank you so much! This has made troubleshooting issues very simple.

Love Spark, its the best for finding trouble plugins. Your server NEEDS this plugin.

A+

This is very pog A++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Perfect for detecting and going over server issues. As always, amazing stuff from an amazing developer. Thank you Luck!

epic profiler!
just great.

Using Spark to test LevelledMobs, Spark made it very easy for us to spot where the plugin was using the most resources, allowing us to promptly solve the issues.

excelent plugin, great job!

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

The plugin is way more better than timings, it helped me soo much on optimising my server, it's absolutely awesome

I never used any profiler before and this took me just a few minutes to figure out how the stuff works, awesome

Excellent plugin, keep work on it! 10/10..
I recommend to all..
Very nice work..

Although I put 4 stars, the plugin is 100% recommended, I only suggest that it be added to be able to obtain information about what CPU the machine uses and the TPS instead of putting 5 seconds, 10 seconds, 1 minute ... putting more time, or at least to be able to configure it to the taste of each one, since the maximum is 15 minutes and you cannot see the performance that has been half an hour or 1 hour ago, I think the ideal would be 5 seconds, 1 minute, 15 minutes, 30 minutes and 1 hour.

This plugin is a perfect tool for generating heapdumps.

A developer using a proper profiler along will this plugin will have an extremely smooth ride patching memory leaks and improving general performance.

I LOVE this plugin. Also that "mister_someone" guy is rating 1 star because it doesn't work on his server only (he is probably on 1.17 or smth lmao)

good plugin for removing lag (Really helped when I had 1 tps, it was because of bees and spark told me that it was using 98% CPU)

Awesome plugin!

Very happy it has per plugin info now!

This plugin is a must-have for every minecraft server. It has a lot of features and if you want to see what resources your server is using and how it is performing.

[07:37:31] [Server thread/INFO]: [spark] Enabling spark v1.5.2
[07:37:32] [Server thread/ERROR]: Error occurred while enabling spark v1.5.2 (Is it up to date?)
java.lang.IllegalStateException: This is not a JSON Array.

Super useful plugin, to always see how my server is performing. I can do nothing but recommend using this amazing plugin :)

there is a version for 1.7.10?ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

Must for all server owners. Should be in spigot/paper. Amazing debugging tool for any issues you have with your server.

dankie for adding search bar back.
Saves a lot of time.

I use this all the time for the incredible built-in profiler and heap summary commands. Luck has continued to far exceed expectations with this plugin and it really shows, as it's become a staple for most developers.

this is called a yay yay plugin

all jokes aside it's really easy to prevent lags & lag machines alike.
I really fine a lot of use to it and I feel like if you own a server you need this plugin.

Honestly the best plugin, this helped me figure out how to lower RAM Usage on tiny 512MB paper instances. Great for developers and servers alike.

must have for servers and developers alike.
.

I'm always running /spark tps when random things happen to see how the server performs at different times with different plugins and player counts, its really helpful. Will always have Spark in my plugins folder

QUALITY. Helped me improve my performance on my anti-cheat. Very cool! I suggest it to everyone.

Excellent for figuring out exactly what the TPS or memory issues are on your server. 10/10

Spark is the go-to tool we use to analyze performance issues and tackle them. Not only is it easy to use and doesn't require any external tools (eg: VisualVM), but it also does a great job of showing what you need.

From using it to better report issues to plugin developers to using at as your own development tool, this is an essential utility for any server.

gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

Perfect for finding whats slowing down your server..............................

It's pretty nice to have this, shows some good and interesting data. Makes it easy to identify the cause of the lag or at least what kind of lag it is.

gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooood

Excellent <3 love this so much^^ yeah the best performance plugin. Thank you very much!

Insanely powerful plugin. ALL serious server developers should have this 100%, no reason not to!

Great plugin, useful for low end hardware server and works as described. Never had problem using this plugin

A must have for every server owner and every developer.
This allows you to find precisely what is using all server ticks and is slowing down the server

Absolutely wonderful little plugin! This is a must-have- the sampler is insanely helpful, and the new tick rate feature is great! I'd recommend this to any server owner and developer.

Excellent plugin for finding troublesome methods inside plugins. It's also good for monitoring general server performance.

A very well developed and feature-filled profiler. This has really helped me put some context to my own personal creations on my test servers. I cannot recommend this any more. Keep it going lucko!

This is resource is insane, hands down the best monitoring plugin on spigot right now. And it's even free. :)

Stills works on 1.7.10. Absolutely essential for optimizing a modded server. Fantastic

Brilliant plugin. Very helpful for owners to check on performance and lag. Highly recommended.

Great addition to paper timings. I like that it can be ran on a shared host, compared to other profilers.

Works very well. Must have on any server. Additionally, you can install it just for the better "/tps" command, and give players the permission "spark.tps" so they can see the tps (but not everything else)

really helpful, design of tps command is really nice. Just the black color is hard to read.

This plugin is very, very helpful for developers like myself.
It easily allows me to detect which part of a plugin is causing lag, and allows me to fix it very quickly.

Very helpfull tool, have been using this to monitor performance for quite some time now. Very easy to use and a lot less hassle than similar software that is run outside of Spigot. :)

In terms of detecting what piece of code is causing lag, this is far superior to any Timings.
Incredibly useful to use as a developer!

Better than vanilla and sometimes even paper timings, great work and a good heap outputter

Incredibly useful plugin from an incredibly useful developer! Thanks for all the work on creating spark!

amazing plugin, helped me identify some of my Skript code performance issues! I think this plugin is useful for every server.

Very useful plugin. Thanks for making this! I definitely recommend!
Awesome plugin like always.

Outstanding profiler plugin! Unbelievably great! Like pretty much everything Luck produces. Keep it going...

AMAZING TOOL!! I was going nuts trying to get Warmroast to work when I found this. It helped me drill down to the exact cause of lag on my server and I was able to eliminate within a short period of time. THANK YOU!!

Great plugin, does what it says and has unique tools for finding the cause of short lag spikes.

Really i don't know what should i say the only thing i can tell luck is best developer i ever seen his plugins are so useful and cool!

The author of the plugin, I love you! This is a development that I did not have.

This is awesome! I don't know if you know this but its already built into worldguard (/wg profile -p 1). However, still great and as always, keep up the great work!

Thanks to Luck for creating this great tool to make timings super easy, instead of using WarmRoast I will now always use this. :)

As a person who is actively trying to reduce lag, this is a much better alternative to Warmroast. Really happy with how I can share the link with other people and how I don't need to go into SSH every time to start profiling things. What an amazing plugin, honestly.

Good no, great plugin, i will use it for debugging my custom plugins performance
