Hello, my server was running on Bukkit 1.0.0 build for about 2 weeks with 20-40 online players without problems. Then i sent a lot of emails and i had to raise slots to 110. 3 days was server running without lags. Then something happened. Server started having lags so we decided to update java and ubuntu. It didnt help. Now we are running the server with 5-8 ticks per second while online are 45-70 players. I updated all plugins and donwloaded new jars. Server is now running on Dev build of bukkit Code: Craftbukkit version git-Bukkit-1.0.1-R1-22-g87867a4-b1637jnks (MC: 1.0.1) (Implementing API version 1.0.1-R2-SNAPSHOT) But server was also lagging while using the latest recommended build Code: Craftbukkit version git-Bukkit-1.0.1-R1-b1597jnks (MC: 1.0.1) (Implementing API version 1.0.1-R1) I start server with Code: #!/bin/sh java -server -Xmx10G -XX:PermSize=128m -XX:MaxPermSize=256m -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:ParallelGCThreads=8 -XX:MaxGCPauseMillis=50 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -XX:+UseBiasedLocking -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=15 -Xnoclassgc -XX:UseSSE=3 -XX:+UseFastAccessorMethods -XX:+UseStringCache -XX:+OptimizeStringConcat -XX:+AggressiveOpts -jar craftbukkit-1.0.1-R2-SNAPSHOT.jar Server was also lagging when i used Code: #!/bin/sh java -Xincgc -Xmx10G -jar craftbukkit-1.0.1-R1.jar This is our server: Linux webserver2 3.0.0-14-server #23-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux java version "1.6.0_23" OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10) OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode) Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz 11GiB RAM I hope that its not hardware issue because server was running fine in the past.

1. The CPU *could* be part of the lag issue. 2. 11GB RAM? Do you mean 12GB? Who do you use as a provider? 3. Try removing most or all plugins and seeing if it lags.
@battlekid 1. CPU usage isnt 100% 2. 11GB of RAM is allocated to the server 3. Internet provider is I think good... and i have problems with low tickrate, not only with lags 4. when i ran server only with NoLagg performace was fine, bud i dont know which of my plugins may cause low tickrate and lags
@Nathan C MySQL is hosted locally. Essentials, Essentilas Spawn, AuthMe (MySQL), EasyBan (MySQL), MineQuery, DynMap, WorldEdit, WorldGuard, Residence, LWC (MySQL), BigBrother (MySQL), Spout, VanishNoPacket, HeroChat, HeroicDeath, NoLagg, Permissions Extended (MySQL), FoundDiamonds, AutoMessage, MyHome (MySQL), KiwiAdmin (MySQL), MineBackup, CraftBall
A few things. You might not want to host the MySQL server locally. It is a RAM hog and disk hog at times Try running Oracle Sun Java 6 (or 7 which is not in the partner repos for Ubuntu yet) JDK and passing -server to the start script (though I see you already have that option. You must install the JDK however, as the JRE alone doesn't have the ability to use -server option. What version of Ubuntu are you on?
It really depends on how you configure the server. If he has a decent amount of RAM, then it SHOULD be run off the same box. If setup correctly, it will rarely use anything close to 1 GB, since the amount of connections is very few. Also to the OP, you have to tune the server.....running MySQL out of the box with no configuring and tuning is asking for bad performance. Also yeah, the CPU is not that great.....my dual core i3 could outpace it all around. If you can upgrade to some Sandy Bridge CPU.
Yea, that is true, I guess. I'm just used to hosting my webserver, on a different server than MySQL (for security and balance), and so I brought that practice over to my Minecraft server. I don't really see performance degradation with this, as I am getting inter-datacenter transfer speeds with 2 hops (Server->Router->Server)
Here is screen of atop when online were 50 players What about BigBrother? Can it decrease the server tickrate?
