eAcelerator, is a PHP optimizer not a DB optimizer.

Hi,

Optimizating my.cnf is a really hard work bur you should optimize it from your server specs..

This whole week i was trying to optimize my.cnf not becouse i am having high CPU usage just for been ready

You can use the command "/usr/local/cpanel/3rdparty/mysqltuner/mysqltuner.pl" into SSH thru putty and you will get some suggestions..

This thing should made every day or every 1-3 days to see what the script will suggest you to change

this is a loong term run so you wont see the changes imediatly

Thank you sady92.
The command you wrote in case you have cpanel, isn't it?
Well, i don't have cpanel, just server run with webmin.
I have red previously about optamization of my.cf , but didn't find anything regarding how to reduce CPU load, only how to reduce the ram usage:

Mybb is optimized to use accelerator, install it

Can you give me the link of the tutorial on how to install it? Iam using Ubuntu 10.04 .
Thank you.

Hey, you can download mysql tuner from here: https://github.com/rackerhacker/MySQLTuner-perl

you will find it here how to install..

I suggest you to not compy ready my.cnf configuration as they are not specified from your hardware confuguration you should tweak this slowly and use this

Also make a Defragment of the Database

@cyper: Thank you for the config. I'll try to compare them with mine and see what to optimize.

@sady: thank you for the link, it seems easy to install.
I will try to install it.

Thanks.
