NoLagg
Version: 1.90.4 | CB 1.7.2
Quote from lenis0012:NoLagg has not been updated since 1.7.10, for more info, check BKCommonLib
Description
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 Read more...
- 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...
Important
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.
FAQ
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.
PTweaks
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)
- org.timedbukkit.craftbukkit.*
- com.bergerkiller.bukkit.common.internal.ChunkProviderServerHook

Metrics
This plugin sends server count statistics to MCStats.org. You can (globally) opt out in the PluginMetrics/config.yml file.
Ok uploaded 1.50.4, fixing chunk errors when teleporting cross-world, also a general fix for NoLaggChunks so to say. Also appears to fix the rain-inside-houses issues.
1.50.3 seems to work well with git-Bukkit-1.8.1-R4-72-ge9ecf57-b1547jnks. Thanks for the quick fix!
Unsure if this is because of Nolagg, but on /spawn or death, spawn location has huge chunk errors. Since 1.50
You can find 1.50.1 on github, it is compatible with the latest 1.00 CB build. (should fix the abstract method error and other issues) It also contains compatibility fixes for BleedingMobs.
If you notice blank signs/missing chunks with that version, please reply here or on the Bukkit forum.
Getting this error with Craftbukkit version git-Bukkit-1.8.1-R4-61-g9dcc77c-b1537jnks (MC: 1.0.0) (Implementing API version 1.0.0 -R1-SNAPSHOT).

Thanks for your help!
does this also help to prevent a 'java heap space' error?
Still have nether problems with missing chunks on spawn. Everything around me loads, but just not the chunk I am on.
Works but messes with the ShowCase plugin, which stacks the item after item which makes the items pick-up-able
@bergerkiller: I am using v1.0.0. This error happens on bukkit 1.0.0
NL 1.5.0 / CB1.0.0 Build 1529 seems stable so far. Thx!
For those that are looking for 1.5.0, the link is: NoLagg 1.5.0
Awesome - thx. So far, so good with the other release. Moving to 1.5.0 with CB1.0.0/1529.
@GravelSocks
Don't worry, today released version 1.50 for MC server 1.00. Simply named it that way because of a 'debug temp build' for those requesting a version for 1.00.
Also, 1.50 should fix the Portal teleport issue with NoLaggChunks.
I am having huge issue when entering the nether through a portal. It seems the chunk around me never loads. I am using the github 1.0.0 version with bukkit 1.0.0
Hi BK -
OK - I will check. I thought that was just referring to bukkit. It would be a little less confusing if you incremented rather than decremented the version. It doesn't really matter that MC has reverted to version 1.0.0.
The whole Minecraft backwards versioning is incredibly stupid. If you're at 1.9.x beta or not, then you either release at that level or go higher, but not back to 1.0.0. They don't seem to know what they're doing from a software process/versioning control standpoint.
@Hvarr
Use the 1.00 version for Bukkit server v1.00. It's under GitHub downloads. Same applies to you GravelSocks, you need to use the 1.00 version for 1.00 and 1.49.3 version for #1337.
@Fatman2778 Re-download ShowcaseStandalone, the author PMed me throguh GitHub that, while I published it, his download was still undergoing verification. Support for that function is on his side.
On CB1.0.0-Build1509/NL1.49.3, when I tried to shut down the server, I got the message: [NoLagg] Performing remaining chunk operations (45767) and it hung the shutdown. Never got past that point.
Any ideas on that one?
