Do you have any suggestion how to tune the solaris to provide the better performance for Solaris? Well, MySQL doesn't just randomly slow down. There's either a software or hardware cause. If you're not maxing out your memory, CPU, or disk bandwidth it's probably a software problem. And, not being a Solaris expert, I don't know where to start if you think the OS is the culprit.

Solaris Performance Issue
Hi, My old mysql is 3.23.56 on RedHat9(Intel). After moving mySQL to Solaris 9 (Sun F280R/2GB Memory) and upgrading mySQL to 4.0.20, I got a lot of complaints about the performance for select and update. Have anyone can tell me if there is anything I should tune for Solaris or MySQL to improve the performance.
