One test is not sufficient. -current is also not the best place to test. :) When I first implemented HTT in -current
The above times seem slow enough to be partly the result of debugging options in -current. I get buildworld times ranging from 1401 seconds (2002/09/01) to 2427 seconds (2003/05/06) on Athlon XP1600 x 1 depending on configuration and tuning (but never with any expensive debugging options). A Xeon 2.8GHz x 2 should be a bit faster than an old Athlon.
Hm, IFAIK I shouldn't have any debug options enabled, but who knows - didn't have time to check more than kernel and malloc.
By the way, attached times shows that using HTT speeds up buildworld by 10 (compare HTT/no-HTT) and this is IMHO a real improvement. Many people buy much more expensive processor to get 10% more speed.
... I did 16 trials (first one was throwaway) of back-to-back buildworlds of the same version of -stable using make, make -j2, and make -j4 for the following configurations: UP, HTT, HTT with smp_idle_hlt, and HTT with pause instructions added to stable and smp_idle_hlt. The fastest build time belonged to UP without any -j option.
All benchmarks using -j are invalid because of a pessimization in make(1). It sleeps for up to SEL_USEC = 100000 usec after completion of every job (average 50 msec). With -j2 this increases !SMP buildworld times of approx. 2000 seconds by approx. 15%. I think it has a smaller effect for larger -j values and for SMP but haven't benchmarked it. This is fixed in NetBSD. I think fixing it was more urgent in NetBSD because NetBSD never changed SEL_USEC from its 4.4Lite default of 500000. 500000 was large enough to be noticeable even in 1997 when it was reduced in FreeBSD.
That would explain the small slow down from -j8 to -j20. But the results seems to me to be schoolbook like: 4 processes per processor as I learned produces best results.
Okay, that's so far.
