What version of MySQL are you using ? Did you load all the data into the database already? –  RolandoMySQLDBA May 21 '12 at 15:33

The first thing you should configure is the innoDB buffer pool size. According to this blog entry by Percona, the ideal buffer pool size is 10% larger than your total data size.

Other settings to add: InnoDB log file size, query cache size.

I have read the blog but how do we decide the total data size is it based on the ibdata files size. I have set it to be per table basis. My server only have 8Gb ram so how it relates to 12G I am kind of confuse here. –  newbie14 May 21 '12 at 12:45
