As per Alan's suggestion I decompressed the kernel source tree with the processes pegged to one CPU then the other, and as he predicted it took vastly longer on one CPU than the other, but I don't know what that implies, or how to fix it. Arjan van de Ven Suggested I run the Linux-ready Firmware Developer Kit on the machine, I've done that the results are here. http://www.homeurl.co.uk/linuxfirmwarekit/ If you missed the thread (and with a high volume mail group like this it's easy to do) it's available on the gooja http://groups.google.com/group/linux.kernel/browse_frm/thread/79f7f9fa39165f55/0e1e7428a54212b5?tvc=1#0e1e7428a54212b5 I really appreciate any help, I've got 3 big harddrives in this box waiting to go into a RAID5 array to replace my ad hoc collection of drives scattered around the network with a data on, most of it backed up or replicated but some not, and as you can imagine I'm feeling a bit exposed.
