Your disks are probably the bottleneck here, and definitely not
the CPU. I have setup two news servers whose daily expires would
consistently take just over an hour. One had 9 2GB drives split
across three NCR53c810 controllers and the other had 12 2GB wide
drives split across two Adaptec 2940UW controllers. The former was a
P133 and the latter a PPro200, both with 128MB of RAM.
My news.daily script would mount -u the spool filesystems async
just before the fastrm phase, then sync the disks and remount them
synchronously. I was seeing upwards of 1000 unlinks per second on the
async filesystem, or 40-50 times faster than a sync filesystem, IIRC.
