NoLagg logo

Version: 1.90.4 | CB 1.7.2

Quote from lenis0012:

in case you are using Orebfuscator, make sure you have ProtocolLib Installed


NoLagg is made out of multiple completely separate components which you can enable and disable freely. Together they offer:

  • Send chunks more gracefully with lowered network stress and reduced processing spikes Read more...
  • Remove entities, resend chunks in case of chunk holes and clean up server memory Read more...
  • Examine server tick rate performance with deep view into per-tick processes of the server Read more...
  • Stop a large amount of items from spawning and spawn at a later time to avoid frozen clients Read more...
  • Stack items with a configurable per-world radius
  • Fix lighting errors that cause clients to recalculate lighting (and thus lag) Read more...
  • Keep track of server performance such as entities, tick rate, memory and more Read more...
  • Fix various bugs the server has (Patches component)
  • Schedule autosaves and force data to be written to disk to prevent data loss on server crash (Saving component)
  • Limit the amount of entities allowed to spawn per world or globally Read more...
  • Watch events closely to warn when plugins execute main-thread methods from another thread Read more...
  • Show a detailed message explaining the cause for a server freeze (lock) [read more]
  • New TNT execution algortithm that is not only more efficient, but also avoids server freezes Read more...


When first installing NoLagg, open up config.yml and disable components you do not need. This is very important, as some components may conflict with other plugins you use, or may not function on the type of demand you have. If you get a warning message [Severe] followed up with a stack trace in the log, this has to do with the main thread not having responded within 10 seconds. The warning is NOT an error and is no bug, and not a bug related to NoLagg. To disable this feature, disable 'threadlocknotifier' in the config.yml. This feature is mainly intended to notify you what plugin is causing the server to freeze, may it ever happen. It is used to debug plugins in general, as they may get stuck for whatever reason. If NoLagg DOES show up in there, it is a bug you should report.


Before reporting any problems, errors, issues, lag or even commenting about it, please read the information on this page very carefully. It makes my and your life a lot easier if you do.

Separating into jar files

NoLagg consists of multiple components you can individually enable and disable. Reasons for not publishing it as a separate jar file for every component can be read here. Please don't ask to separate the components, I will just link you to here.

Spigot server

Not all components are needed when you use the Spigot server. The ItemStacker, ItemBuffer, Spawn Limiter, Thread Checker and Thread Lock Notifier components are not needed, since Spigot has it's own implementations to deal with that. If you still wish to use one of these components, you can, but it's best to disable the Spigot alternative then.

The other components (such as TNT, Chunks, Lighting, Common, etc.) are not implemented in Spigot (yet?) and offer additional functionality.


Since people keep asking about this, I went ahead and compared the two plugins. I am not going to discuss which is better in functionality, I'm just going to state which features overlap and which do not. Both plugins offer a TNT-lag solving solution, feel free to choose which solution you like better. (the solutions are different) Both plugins also offer a way to change when and how chunks are saved, NoLagg adds to this that you can configure when the server writes data to disk. PTweaks offers a way of showing used memory, NoLagg Monitor too with a bit more information. Again, preference. Chunk Persistence is something PTweaks offers and NoLagg does not. Reason I excluded it from NoLagg is that the implementation used up more processing power than that it solved (I did have this for a while). If you want to give it a try, PTweaks is your answer. Monster Limiter is incorporated in NoLagg as well but then for all entities, and more options. ChunkEdits is a tricky one: NoLagg chunks does something similar, with the difference being that it also changes at what rate chunks are sent, which is the main feature NoLagg chunks offers. In addition, the ability to increase the amount of threads running to process chunk packets and the re-using of packet raw data offers some benefits PTweaks does not offer.

Then there are a lot of other features NoLagg has and PTweaks does not, such as examining server tick rate, item stacker, item buffer, fixing lighting, cleaning up server memory, resending chunks, removing entities on command and others (see description).

In short: Both plugins offer some overlapping features, and you need to pay close attention to the configuration of PTweaks and NoLagg and disable things that conflict. Having two TNT explosion altering plugins is going to have strange results, for example. Compare the functionality, decide, and enable in NoLagg what you do not want in PTweaks, and vice versa.

NoLagg showing up in error stack traces

The examine component inserts various hooks into the server to gather measurements. Specifically, you will find that the following lines show up now and then. These hook classes do absolutely nothing when not examining and can not be the cause for any issues, unless the stack trace ends there (first line after the exception shows this stack trace)

  • com.bergerkiller.bukkit.common.internal.ChunkProviderServerHook

    A lightweight version is nice but what are the features that will remain in that version?

    PS: Maybe its better for the lightweight version to exclude the things that are present in spigot, a lot of the servers run spigot too and that would save time and make it easier right :)

    Thanks for 1,000,000 downloads guys!
    I have been looking at your requests, and a lot of you are sad about the fact that NoLagg break every update.

    It is a choice we had to make.
    There is thousands of lines of code in Nolagg and BKCommonLib.
    They are some of the biggest plugins out there, and they are based of NMS (Minecraft internal code)
    This nms changes every update.
    Even tho nms changes every update, you can avoid having your plugins to break using reflection.
    We use reflection in a lot of places, but the amount of code we use is so large that we can't really avoid all of it.

    I have summer vacation and therefor time for 1 new big project.
    I want to let you guys choose:
    Work on the current NoLagg and fix all bugs i can spot
    Make a lighweight versionof NoLagg that does not break every update.
    Recode NoLagg entirely improving it but still breaking every update

    I love nolagg, however I would wish it did not break everytime minecraft is updated. I guess that is easier said than done, but if it was possible it would be great!

    Is it so that only some components of nolagg does not work when updated? and if so is it possible to make it so nolagg just disable that feature instead of the whole component.

    I guess the reason for it to stop working also can be because of BKcommonLib, if so is it possible to make nolagg depend on protocollib instead, since it seems to work even after a update of minecraft.

    Im not a programmer so excuse me if I speak nonsense.

    I hope this gets to 1.7.9 soon since MC has moved on to 1.9.10, and there is no 1.7.5 craftbukkit beta to use 1.90.5 with. Just this and Worldguard are the only two holding up the upgrade parade. This only works with chunk functions disabled in 1.7.9. And that doesn't do much good since that is one of the primary things I use it for.

    @KnightcraftRPGServer: Go

    Perhaps, it has been some time since I've used this plugin. I certainly will not be going back to ClearLag though xD

    I can only hope that this one will become fully compatible with 1.7.9 again and I won't have to disable some of the features of it to get it to run smoothly.
    Still working wonders though, as usual. :3
