The dual 4100 here is still cranking through a -j 8 world. What's the appropriate -j level for an MP box, anyway? I just naively used -j 2. Should I go higher? I realize going higher will be a better stress test, where does the overhead from cache pollution & extra scheduling outwheigh the possability of having another job whose I/O has completed & is ready to run? At least on a modern UP, like my tbird, omitting the -j seems to speed things up slightly..
