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,
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 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.
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.
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.
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
This command will bring up most ingame settings, and information. You can also enable or disable mob spawning from ingame.
This will show current ram usable, and information

Please consider donating to help support development of this plugin!
1) Cyberpwn $5
Those are just there if your flying, if you get close to the chunk, they become visible
Next update, ( i hope ) Ill add op support.
@Dimitrias Post a picture of this, your plugins and your specs. No one will know why until you do.
It only increases RAM by 200 instead of decreasing, why?
You really should add OP support for this. also even when I add the default to OP in the plugin.yml it isnt working :(
Also allow the console to use the RAM command
Once I installed this OPs were getting invisible chunks. Any way to fix?
Could you make it that if there is no permissions file detected, that it defaults to OP? On my small server we don't have permissions, because there is only 5 of us playing on it and I have put this plugin on our server and it works great, but OPs can't use command /ram and we'd like to use it also without setting permissions just because of this command.
How do I set minimum monster amount?
I just tried it on my main server and with 50-60 players online my TPS were 10-14 after I added the plug in it went down to 4-5 TPS D:
Like i have previously said, There is to many variables and it won't work on every server. I am unable to test it with every variable option
Not a Ptweaks error i can find
How can you prove this really helps with I/O? I am still seeing high I/O usage with this plugin.
edit: This plugin causes my server to read time-out on /save-all. I also made sure that the chunk persistence stayed within reasonable limits. I like how you say "This will no longer need extra ram.", it caused a 6 GB higher load than normal. Do you know how RAM works? If anything this helps CPU, but it didn't.
got this >> http://pastebin.com/PpHRjJhK
ok its fixed ^_^
Everyone Ptweaks V1.6.1 is missing the plugin.yml I have just updated to 1.6.1- But it needs to be approved, the version is already on the forums page download there until that version is approved here
It depends really
Ill see about adding something like that Or that can limit any entities
What about an option to fully remove experience orbs? it causes tons of lag. All other plugins doing the same are dated
Is this usefull with RAMDISK ?
Give the permission ram.has to anyone you want to use it
93MB means how much your using, I think i got the messages backwards
