weird mini lags

[andr3iu7z]

tell me if its ok now because today i bought a new machine(24 gb ram) and when it reach more than 400 players its start to have like you weird mini lags.

LE: I have Linux. how that file should look at me GameServer_loop.sh

Go to this topic and start reading.

Make sure you will read this as well (only this is enough to make you run over 2000 people.)
http://l2-adrenaline.com/linux/L2DCLinu ... elease.pdf

and finally this
http://www.mysqlperformanceblog.com/

For sure you have to change the default setting.

for a quick fix add this to your GameServer_loop.sh
Note* This is configuration for 8 cores cpu and over 12GB of RAM, if you have 4 cores then change -XX:ParallelGCThreads=3 <--

Code: Select all

java -server -Djava.util.logging.manager=com.l2jserver.util.L2LogManager -Xms2048m -Xmx5000m -Xmn512m -Xss128k -XX:ParallelGCThreads=6 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=31 -XX:+AggressiveOpts -cp ./../libs/*:l2jserver.jar com.l2jserver.gameserver.GameServer > log/stdout.log 2>&1

if you see server is unstable remove -XX:+AggressiveOpts

What do you mean "unstable"?

[dinor]

strange lag
not working the way it should etc.

[andr3iu7z]

dinor i see u really wants to help so i ask you something. 1 week ago i had a machine 8gb ram all works good till ~1.2k on and lag startng. Now i have a new machine and on 800 + starts lagging with same config like the other one
The new machine has 24 gb ddr3 ram and i dont understand why.

[dinor]

well... you haven't say the exact server configuration.

Know that performance is based on:

Hard Drive -- If yuo want performance you get the faster drive for read/write data -- SSD are now even better than HDD 15k RPM

2 Hard drives -- One for OS - GamseServer and the second exclusively for database.

RAM which you have plenty, but also RAM allocation for Java and MySQL

MySQL optimization -- default settings are not for big servers
Java optimization -- like in startGameServer.bat or GameServer_loop.sh

CPU -- 8 core is cool, but 4 cores is fine as well

Do not run website in the same server as the GameServer.
If possible LoginServer and CommunityServer in different server

Network connection 100Mbps is enough for 1000+ people

Thread Configuration in L2j configs (i don't really know what a good config is for this)

[andr3iu7z]

What to change at mysql config except max_connections?
I dont have community server.
It is raid hard so i think i cant make mysql and java runn on different hards?

[jurchiks]

which type of raid? raid0, raid1, raid5?

[andr3iu7z]

raid1
i have hetzner server eq8. i bought this and not bought eq9 because this have 24 gb ram.

[jurchiks]

well, you could just attach a third hdd for db

[Raikkon35]

I take this thread to ask one thing. If this is not a good place, let me know and I'll put it on another.

Which is better, 2 SSD in RAID 0, with everything installed, or an SSD to the server and the other SSD with the database?

Thank you!

[jurchiks]

imho server and db separate on each...

[dinor]

imho server and db separate on each...

+1

1st SSD OS / L2j Server
2nd SSD MySQL

Thank you friends!
