[Resolved] Mysql 5.1 x64 issue - Hight CPU load (1 reply)

Hello,

I just setup a new MySQL 5.1.52 x86_64 server and my application works fine except for few queries that generates a high CPU load. The execution time of those queries can take up to 4mins!

My server:
CentOS 6 MySQL 5.1.52 x86_64
8 * Xeon QC E3-1220 - 3.1GHz
8GB RAM
MyIsam DB engine

FYI, those queries work fine on another machine with the following configuration:

CentOS 5.6 MySQL 5.0.77 i386
1 * P4 3Ghz
2GB RAM
MyIsam DB


Basically, I have tried to update and tune the mysql configuration file whithout success. I also used default mysql configuration like my-large.cnf, my-huge.cnf, etc.

Could you please help me?
Thank you!
