I'm really stumped here.
I have two seperate machines... one very high end, dual CPU machine, raid
5, etc, the other is a piece of crud (standard low end workstation).
Both machines are running Redhat Enterprise Server 3...
the SMP machine is running the redhat 2.4.21-4.ELsmp stock kernel...

Yep. Can you please run 'vmstat 1' while the test is running, and
redirect the output to a file? vmstat can help spot all sorts of issues.
Also, what filesystem and disks are you u

Today, we upgraded the machine to the latest redhat ES 3.0
with kernel Linux 2.4.21-15.ELsmp -- no luck... imtest -z still took 19
seconds to run... compared to 2-3 seconds on the cheapie machine.
I generated the traces requested, but I'm not really sure what I'm looking

Hm, you said SCSI Raid - that can mean alot.
Could you run a good old bonnie on both boxes and

Hm, this is bonnie 1.x, which is okay, but it has 2Gb filesize limit. Your
big box has 2Gb of Ram, right? How big was your file size with bonnie? To
make this test work, boot both boxes with mem=128M as kernel parameter so
it will only use 128M of the memory. Then,
