Anyone know a good way to find out if disks are a bottle neck?
Right now I'm running mysql for ubbthreads on a IDE software RAID 5 system. The drives are 7200rpm and run pretty well. In that system I have a 15k RPM SCSI drive as well.
I'm trying to figure out if purchasing a couple more SCSI drive and make it a raid5 would be worth it, hence the question on determining bottle necks.
CPU load now is between 30-40% on a Dual 1.1 PIII, and if going to SCSI gets me a bonus year, it's probably worth it. (already have 2GB Ram onthe system).
TIA
Fred
