Server performance...

[LaraCroft]

Hi guys....

One question...

What is the better config for file GameServer_loop.sh??
Im using default config:

Code: Select all

#!/bin/bash # exit codes of GameServer:#  0 normal shutdown#  2 reboot attempt while :; do	[ -f log/java0.log.0 ] && mv log/java0.log.0 "log/`date +%Y-%m-%d_%H-%M-%S`_java.log"	[ -f log/stdout.log ] && mv log/stdout.log "log/`date +%Y-%m-%d_%H-%M-%S`_stdout.log"	java -Djava.util.logging.manager=com.l2jserver.util.L2LogManager -Xms1024m -Xmx1024m -cp ./../libs/*:l2jserver.jar com.l2jserver.gameserver.GameServer > log/stdout.log 2>&1	[ $? -ne 2 ] && break#	/etc/init.d/mysql restart	sleep 10done

My test server is a Quad Core Xeon 2,5 Gh whit 4GB DDR2...

Is better to use all memory on -Xms1024m -Xmx1024m options??
Or i use only memory needs to run the server??

Thxxx and respect

im not any super expert.. but i have read that adding -server parameter speed things up a bit.. here is what i use ( i have 8gb ram tho..)

#!/bin/bash

# exit codes of GameServer:
# 0 normal shutdown
# 2 reboot attempt

while :; do
[ -f log/java0.log.0 ] && mv log/java0.log.0 "log/`date +%Y-%m-%d_%H-%M-%S`_java.log"
[ -f log/stdout.log ] && mv log/stdout.log "log/`date +%Y-%m-%d_%H-%M-%S`_stdout.log"
java -server -Djava.util.logging.manager=net.sf.l2j.util.L2LogManager -Xmn1024m -Xms2048m -Xmx4096m -XX:PermSize=256m -XX:SurvivorRatio=8 -Xnoclassgc -XX:+AggressiveOpts -cp ./../libs/*:l2jserver.jar net.sf.l2j.gameserver.GameServer > log/stdout.log 2>&1
[ $? -ne 2 ] && break
# /etc/init.d/mysql restart
sleep 10
done

i also have some other parameters in there.. not sure if they help tho.. anyone with some good expirience on these?

btw my file is for final.. dont c/p and try on epilogue.. just add the parameters in red or something..

I use all "static" (e.g. weapons, armors) tables in MyISAM and several large tables (characters, items) in InnoDB, due to several problems.

nice idea

Xss (thread stack size) set to 128k is at the lowest bound. It's not recommended to set it smaller, so 256k stack is enough for an L2j server program. ParallelGCThreads should be left on the default value. It's not recommended to set it higher than the number of cpu cores. Not everyone has 6-core cpu in their machine. Anyways, everyone should do their own tests to get the best options for performance. But you know, performance in some cases is like the principle of "quantity over quality". So, some performance-like options may cause server crashes and a lot of errors in the gameserver.

would add, with a -XX:+AggressiveOpts I strongly jumped CPU usage,
