No S-S? All the 060 caches would have been disabled, hampering performance. Use the 060 cpu command to turn them on. Such as "cpu060 b or cpu60 best" or whatever option it is with your particular cpu command (I can't remember details I'm afraid).
Also, large amounts of copying will stall unless you have plenty of disk buffers. For example, addbuffers dh0: 1000, addbuffers dh1: 1000
Well, he could also try to run setpatch, which not only puts the caches on, but might also fix some of the devices, which could also speed up copying.
