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. -- Brian Tao (BT300, taob@risc.org) "Though this be madness, yet there is method in't"
