pTweaks
Hello,
Unfortunately, I have long lost interest in Minecraft and have no plans to update this plugin any further, so I highly suggest finding a replacement. It was a good run, but I think it's time to call it quits. We appreciate all the support over the years, and are truly grateful for it. Best of luck,
Cheers.

pTweaks is a server optimization tool. This plugin will redefine how your server loads, stores and manages chunks. pTweaks will prioritize chunk loading so the ones that need loaded get done first. When a large number of chunks are being loaded consecutively the plugin will start to unload unused chunks at a higher rate to keep performance on the server higher. pTweaks has a smart chunk loading algorithm so that chunks in a players surroundings stay loaded while under normal use so never again will you take a few steps and all the chunks start to unload behind you. pTweaks stops your server from using resources it doesn't have to use. pTweaks also adds mob handling. You are able to set limits of Monsters and Animals in each world. When things get out of hand pTweaks also offers a kill command to kill all living entities. pTweaks also offers a command to check your ram limits, performance, and allocations. pTweaks is an anti lag plugin.
Your server will be able to run longer, and smoother without the need of a restart. This being pTweaks already clears all unused data that would normally be removed with a server restart. Java dumps are already cleared and Chunks have a longer life span, meaning ram usage and CPU intensity will drop. Mob handling is now a possibility, enable or set the amount of mobs/animals spawning in your world(s) to massively drop resource usage, Limiting mobs is like turning down view distance improvement wise. Helps reduce performance therefor stopping lag.
The lifetime is how long the chunk is loaded into memory, and the prune is the cycle rate. Depending on your server size and CPU power you may want to customize these settings. Larger servers with more free ram may want to make prune higher to keep chunk loading and unloading from happening less often, while smaller servers may want to keep the default settings or make prune lower. The prune is the cycle of when all the unused chunks get unloaded. So having this higher makes more chunks stay loaded longer, while having it lower makes them unload faster. Both have benefits but generally i don't suggest editing it. SpawnChunkRadius is the static (initial) loading of chunks when a player joins your server, so the amount of chunks loaded around him, don't suggest editing this.
ChunkEdits:
ChunkEdits is a 100% customized chunk loading algorithm to enable quicker loading of chunks, and priority packets. So chunks load in a fashion better fitted for the player and the server. This algorithm isn't perfect, and currently being recoded.

Monster Limiter:
This is a fully custom feature. You can enable or disable this in the config. Limit the amount of Mobs or Animals spawning in your world, or disable spawning all together. Change if you want spawning in one world and not the other, you can also simply use the kill command to butcher all living mobs/animals in the current or all worlds. You can see all commands by typing /pTweaks in game.
<><><><><><><><><><><><><><><><><><><><><><><><><><><><>
Chunk Persistance:
This is a fully custom feature, that can be turned off in the config. This does a whole lot and is the main backbone of the plugin. Change how many chunks are loaded on player join or how long chunks stay loaded after people leave them. Makes chunks with no activity loaded at certain intervals to save tons of CPU power. The clear cycle is changed to make less disc writing. Chunks with lots of visitors will stay loaded longer, and not have to render again and again. This adding lots of performance to your server.
<><><><><><><><><><><><><><><><><><><><><><><><><><><><>
Ram Check:
Check the amount of ram being used, the free ram, and currently loaded ram. This gives you the ability to check server performance and debug bad plugins by seeing which are taking up the most resources by adding one and testing, adding another and using the command again. This command will soon also have TPS and other performance tracking abilities.
<><><><><><><><><><><><><><><><><><><><><><><><><><><><>
Packet Auto Save:
Instead of writing every chunk to the disc every 2 seconds. This changes it to a custom time that you want, Default is 50ms This saves the server from writing about 14KBps to the disc (10 writes, 3 reads per chunk, on a 3 person server). As well as saves about 2 calls to deflate every 2 seconds. (per chunk)

TNT Edit: (Suggested)
Basically all this does is after the first explosion, shadows the rest of them by duplicating the same explosion so the effects of say 500 TNT are the same as the effects of a single tnt block going off. This is not bullet proof, and it will still be possible to cause server lag by making the server render too many packets, but this is not possible unless doing thousands of blocks with a plugin like WorldEdit.
- Download pTweaks
- Stop your server
- Put pTweaks.jar in your Plugins directory
- Start Your Server
- Edit Config's to your liking or leave default
- Reload
- Done!
/pTweaks
Permission: pTweaks.pTweaks
This command will bring up most ingame settings, and information. You can also enable or disable mob spawning from ingame.
/ram
Permission: pTweaks.ram
This will show current ram usable, and information

There isn't a huge benifit. It just depends if you want better ram use this, if you want better cpu use Nolagg
Demonstrate how to use Monster Limiter?
Help me understand this: Server has 3gb ram. I am alone on the server. myMcadmin say i use: 280/3072
/ram say i have 93 mb ram free. Free / Total: 93/2730
If you are an op, but there is no permission file, you cant use /ram.
You say you could use this and NoLagg, but it seems to me that there is ALOT of overlap. What benefit would I get form using NoLagg and PTweaks together?
@htmlperson
It sure could. You will just have to test for your self. Thinking of the functions then yes
I have MineOS, which already stores all data in ram and writes to disk every hour. Will this help me?
@deleted_7267305
One. I did not include Pex support nor will i ever do so. Two, It does not support the * node so you will have to have ram.has permission. three, l will look into that bug, Thanks (however i can not recreate this)
for some reason /ram says i dont have permisison both in game and even in the console window. Im op and using PEX with '*' permissions
edit: also if you have enable-flight=false and chunk persistance enabled you get kicked for flying for being AFK for roughly 10 seconds. Confirmed that this is the cause.
@FiddyCraft
Well, your server has 3GB max and it is using 2,700MB your free ram is 300MB So its not wrong....
2424/3023 isnt much different then 308MB / 3GB
Free ram is how much you have left not how much your server is using.
when I use /ram 308/3026 when i use lag meter its 2424/3026
My question is >_> why these differences
and why does it say my free ram is only 308
I have run into problems with (temporary) chunk persistence causing lag in the past especially if kept for too long in memory. I would advise anyone using this (awesome) plugin to keep in mind that keeping chunks in memory based on traffic for long periods of time can cause problems if you have flight enabled on your server. Issues can also arise if your server has vast minecart tracks. when it comes to keeping chunks in memory it is a balancing act that you have to get right for YOUR server. The key if you get this kind of lag may be to change how long those chunks stay in memory. I have seen explorers eat through a gigabyte of memory in their travels. (my map was 7 gigs at the time :P) there is no drop in solution for everyone. When used widely this plugin (and others like it) can be a valuable asset to any server let alone one running on lower than recommended system specifications.
Updated 1.6
@ewized
They only reason that would happen is if your have no Extra CPU Hundreds of servers are using this with the opposite effect
With this i got lag and with out it i dont have lag.
@yurikoma
That is really weird If you have bad CPU that will happen since this takes some CPU
don't know why but when logging in to my server i seem to lag a lot more then without this plugin
It wont let me update the File. Go here for version 1.5.1 http://forums.bukkit.org/threads/mech-edit-ptweaks-v1-5-1-remove-all-server-lag-1240.39399/
@rusty3995
Version 1.5.1 fixed this Oh, This build is way outdated :l I dont keep this updated like i do the bukkit forums thread
@iN94
Maybe soon :P
