I used to use a dual xeon 400, with 512mb of ram, and ultra-wide scsi
disks, and i used to poll about 115,000 interfaces every 5 minutes.
we ran 5 processes in parallel, or it took about 11-12 minutes to complete
a cycle.

the OS was freebsd.

that was a couple of years ago, though.

Recently I had another server that was running on two 10gig ultra-66 IDE
disks, running linux, that was performing horrendously, and crashing a lot.
I upgraded the disks to 2 18g ultra wide SCSI disks, and the box has been
performing flawlessly since.
This box was mosltly running a webserver, though it did some other stuff.
Nothing that should have put enough load on it to matter, though.

just reaffirms my long standing prejudice against IDE drives.
(no flames, please)

It does sound like the box should be performing better, but I can't 
really say what might be the problem. 

What OS are you using?
