Yup, it's definitely fedora's fault, not my hardware.

There is a long talk on the test mailing list about this (it started up
before FC3 went final, and it stayed there. You may be able to get some
assistance from there.

Can you not just unplug your systems cd-rom drive and see if you get
that performance back? This would be a quicker and cheaper initial test
then buying new hardware?

I always thought it was bad to have a  CD-ROM on the same bus as a hard
drive as the overall speed of the bus dropped to that of the slowest
common denominator (the cdrom drive).

And of course having two hard drives on the same IDE bus, was also bad
as you shared the bus resources and could not access both drives at the
same time.

Thankfully SATA resolves these problems, as there is only one device per
bus...
