That's nuts: SCSI disks cost a lot more than comparable IDE disks.

Your example is not very convincing. You want to compare a good SCSI
controller with a bad IDE one? That's not what one would call equitable.

Consider: let's get an antique 50 pin adaptec SCSI controller, and compare
it to a 3ware escalade running RAID 0 over 4 drives. The IDE one is faster!
It saturates the PCI bus! The SCSI controller pokes along at 10 MB/s.
Doesn't prove anything.

The business about CPU utilization did, in fact, use do be an issue, but
hasn't been since the introduction of UltraDMA IDE controllers, which
was a few years ago. (Admittedly, if you've been running WinNT 4 all
this time, you haven't been able to take advantage of it.)

This was a major issue in 1996. It's been solved for several years now, but
the perception of Java having a speed problem remains.

Java stored procedures are the #1 most-desired-by-me feature for PostgreSQL.
Oracle and Sybase are examples of databases that have this feature already.
(Strangely, Microsoft's database doesn't have it :-)
