the backend is on a completely separate machine (with no frontend
duty), its an Athlon64 3200+ as well, with 1GB of ram and the RAID10
recording array.

The AthlonXP does not have the recordings drive mounted via NFS, the
Athlon64 does(it runs a backend process occasionally for firewire
recording), but unmounting and using just the backend protocol does
not speed things up any. I also compiled in the patch in SVN that
forces the frontend to use the backend protocol even if the recordings
drive is mapped, this didn't make any difference in speed.

I should also add that on the Athlon64, when I'm in the Show list
(left side tree), the scroll speed is fine, its just that as soon as
the title list is active things slow down, not just scrolling between
shows, but also pressing right to open the show menu takes some time.
