My experience has been quite different.  Granted that SCSI is faster, 
and true hardware-based SCSI RAID 5 is yet better, but my server runs 
two EIDE disks and responds just fine for 25 users running OO.o, 
Mozilla, and the GIMP.

I would still check out memory usage stats.  Program loads should be 
very quick after the first time someone runs it, due to the cache.
