I took some time to play with a machine and test ubench scores on it for few OS. Machine is AMD64/939 3000+ with 2GB RAM
(dual-channel).
I took ubench, because it does not deal with systems other than CPU and memory which usually says something about
efficiency of OS. I tried to optimize things by alwyas using flag "-O" and removing all debug stuff from kernels. Since
this was all done on the same machine I think we can kinda compare those results. I used FreeBSD 4.11, FreeBSD 5.4/i386,
FreeBSD 6beta3/i386 and FreeBSD 6beta3/amd64 in this test.
Summary
Latest DFly-preview has best Ubench AVG of 106030, because of 2nd best memory score (124353) and balanced CPU score
(87707). Also good was FreeBSD 6beta3/amd64 with Ubench AVG of 101448, because of balanced CPU (102455) and memory
score (100441). Seems like extra registers in long mode help quite a bit. Third was FreeBSD 5.4/i386 with Ubench AVG of
94304 - mostly because of best memory score (130602) and not so good CPU score (58006). Hardly behind was FreeBSD 4.11
with Ubench AVG of 94296 - decent, but slower CPU score (84431) and very nice
memory score (104161). FreeBSD 6beta3/i386
was severly behind all of them with Ubench AVG of 55968 - with cpu of 59138 and
memory of 52799.
I wish DFly had better CPU score :) But it still has best score among 32bit OS
systems!
As usual, YMMV :)
