OT: MySQL performance when the problem isn't Perl
You're not using Oracle|SQL Server? You're on your own
As someone who deals with Oracle server, I often feel very much alone when it comes to diagnosing server problems as Oracle's frontline support gets worse with each passing year.
That being said, my tuning woes have been ameliorated by throwing more memory at the problem in addition to common sense tips like putting indexes and tables on different physical disks and tuning the efficiency of my sql.
