This patch replaces ULE > with SCHED_SMP, which will now no longer exist as a seperate fork of ULE. Not very scientific nor precise but using 4bsd as scheduler 'make -j 3 buildkernel' completed in 11 min. 58 secs. and ule did the same in 13 min. 26 secs. So ule seems slower. This is on a dual zeon @ 3.2 Ghz (the first 64-bit from Intel, not very fast but hot) and 3 GB ram and 15 RPM scsi-disk with /usr on zfs. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner.
