    Lag Test 3,000 TNT / With and Without Ptweaks (356MB server)



    Ptweaks is plugin to optimize your server, by changing chunk loading algorithms. Ptweaks is also huge on ram reduction, if you run a low ram server, or just want the improvements; Ptweaks is for you. Ptweaks also stops crashing and lag from TNT, and enables complex methods to improve your server in almost every aspect. Running a 16GB or 512MB Server, Ptweaks is for you.


    We ran 7 large plugins on a small 256MB server without PTweaks. The server couldn't load chunks, there was noticeable amounts of chat and block lag. The server was all around unplayable. We enabled Ptweaks and within minutes of being on, the chat and block lag we're gone. Chunk's loaded normal as they would on a 3GB Dedicated server.


    • Massively reduces needless disc usage
    • Loads Chunks faster
    • Priorities Chunk's in the direction your facing, To ensure smooth game play
    • Keep chunk's loaded at a configured amount
    • Chunks with higher activity such as a spawn, stay loaded to massively reduce Ram usage
    • Limits Mobs and Animals to a configured amount
    • Disable Mobs and Animals
    • Check Current Ram being used
    • Config file's for each part of the plugin
    • Dupe TNT Packet's, So TNT will no longer cause any server side lag
    • Add's highly advanced Chunk Algorithms
    Feature Description:

    AutoSave: Instead of writing every chunk to the disc every 2 seconds. This changes it to a custom time that you want, Default is 30m. This saves the server from writing about 9KBps to the disc (7 writes, 2 reads per chunk, on a 3 person server). As well as saves about 2 calls to deflate every 2 seconds. (per chunk)
    Chunk Persistance:
    This is a fully custom feature, that can be turned off. It will change how long chunks stay loaded. 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. This works for people just joining on that chunk or someone walking into it, So a spawn point works great with this. You can change how long they stay loaded, and how fast they unload. Default works for most though. This will no longer need extra ram.
    Monster Limiter:
    This is another fully custom feature. You can change it to a certain amount of Mobs spawn, or if they spawn at all. You can turn Mobs off and animals on, or vice versa.You can set a minimum mob limit and a maximum, That the server wont go below or above. Fixing some lag that can happen from mobs spawning or not spawning at all.
    When the server starts to save, It slows down the processes to normal speed, Causing the save to be instant.
    Ram Saver:
    Based on how the Ptweaks edit chunk loading, Ram drastically goes down. With the added features, such as slowing down disc usage. You can see up to a 80% Improvement
    Chunks in front of you get a higher priority too load then the ones to your side and back. Making smoother game play, and instant chunk loading.
    TNT Edit:
    This makes TNT only really have to load once, then it is saved until the TNT packet stops. Causing TNT cause no lag at all, Under 10k TNT, which it will start to give off lag. TNT packets are also saved, after the first and just duplicated so you dont get spammed with them, and causing lag.
    1. Download Ptweaks
    2. Stop your server
    3. Put Ptweaks.jar in your Plugins directory
    4. Start Your Server
    5. Edit Config's to your liking or leave default

    Will your TnT method work along side NoLagg's do you think? Should I disable one or the other?
  6. Offline


    4 different people on different servers excluding mine (which works on multiple accounts)
    Can prove its not the plugin. Make sure to reload

    Should be fine, however running both plugins may not help much at all

    Hmm, in terms of acting against one another? I like NoLagg for its entity removal commands. /nolagg clear, clears all xp, dropped items etc... Do know know of an alternative? I have experienced TPS lag before, used the command, and it cleared up.... Could be coincidence but I don't know...
  8. Offline


    yeah can you add a drops clear option?

    We ran 7 Plugins, and 5 Players on a 356MB server, Without Ptweaks.
    The server had Chat lag - Block lag - Chunk's were loading quite slow.
    We added Ptweaks and within 5 mins, All lag was gone, There was physically no lag at all.
    Blocks - Chat - Chunks worked smooth as if they were on a 2GB server.
    Even when saving.

    Block lagg and chat lagg are caused by internet problems... How can the plugin improve that? That isnt possible right? It can only reduce RAM usage, can you give examples of that?
  11. Offline


    Having slow loading chunks can cause block lag, Low ram and the server can't handle all the messages or the other process's its doing so chat becomes laggy.

    I have tested on Groupmanager which bridges to Permissions fine.

    when I use /ptml rm and /ptml em it enables and disables mobs server wide.

    Is there anyway to use this plugin to do it on a per world basis?
  15. Offline


    hmm it should be already that is one of the features 1.6 should have had.
    Ill look into fixing this asap.

    Mob limiting doesnt work, 2500 set in config, 3800 in the world atm. Used a butcher and now there are only 500 mobs after 10 minutes.

    Wow, I have never had that happen.
    Is this a new thing? No one has ever said anything but Moblimiter and it has always worked for me.

    Hi i have a problem.

    Computer specs.
    I7 with 12 GB ddr3

    i use the bukket server with 2 plugins

    as a 3rd plugin i tried the Ptweaks.v1.6

    but i each time i try to play on the server. im the only one atm i get out of memory

    on the server it says" Can't keep up! Did the system time change, or is the server overloaded?
    but also gives other java error's

    i use " -Xmx1g "

    when i try to give it more memory by change it to 2g it gives an error.

    Error occurred during initialization of VM
    Could not reserve enough space for object heap
    Could not create the Java virtual machine.

    there should be enough memory free seeing it has 12 GB memory.

    what am i doing wrong ?
  24. Offline


    If you have 12GB memory and 2 plugins, you don't need Ptweaks =)
    Give it 10GB see if you still get the error.

    i was still using java 32bit on 64bit win7 so i just installed 64bit java and i can use more memory.

    but how is it possible it run out of memory when im the only user on it?

    i didnt play yet will try that now and see if it still says it.
  26. Offline


    With that much you shouldnt.
  27. Offline


    im still playing till now so i guess the cause was that it was java 32 bit no idea. We\ll see :)
    Thx anyway ":)

    Any idea on when we can expect the fix for disabling mob spawns per world? My users are moaning at me about endermen destroying their creations on our creative world :D

    Cheers for all the good work.
  30. Offline


    It shouldnt take long at all, I just want to release the bug fix in an update

    That's great but this plugin stops any other plugin that stops mob spawning from working so I'm essentially stuck until you update.
