Does the mysql in centos compiled with multi processor support? i have a mysql in centos 5 running in a core2duo processor and it seems that it only uses 1 processor.

How many tables are you querying in MySQL?

If you use MyISAM tables (still the default), only one thread can access a table at a time, so you won't get more performance out of SMP to accesses to the same table.

Hi,

What do you recommend me to do so i can optimize my database on a multi-core processor? and i haven't got an answer for the mysql package for centos 5 is the multi-threading supported?

Thanks!
