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.
