We're running MySQL as web site backends, with about 40 queries/second
at peak times. The system is Linux 2.2 w. 2 x PII 400, 256MB RAM.
At those peaks, the system becomes almost unusable. (I have to admit we
have a higher percentage of updates, for we're counting page impressions
in the database. Maybe there are also some problems with large joins
that have to be performed in order to have count()s.)
Now, I'm curious what sort of HDD subsystem you're using. We're running
(don't hit me for that) a RAID5 UW SCSI system with 5 HDDs. How much
performance could I gain setting up a RAID1-0 (striping over mirrors)
array with 4 HDDs, dedicated for the mysql tree?
