I have 4 identical PC with FreeBSD (2x4.11R and 2x5.4R)
Results (/usr/ports/net/benchmarks/nbench):
(CPUTYPE=p3 in /etc/make.conf; portupgrade -vf nbench)
tests:
NUMERIC SORT: 4.11= 499.52 494.31 5.4= 451.26 449.7 (4.11 faster)

LU DECOMP. 4.11= 225.94 226.76 5.4= 211.56 210.84 (4.11 faster)
original:
INTEGER INDEX 4.11= 12.305 12.238 5.4= 13.409 13.400 (5.4 faster)
FLOATING-POINT 4.11= 9.309 9.296 5.4= 9.052 9.041 (4.11 faster)
new:
MEMORY INDEX 4.11= 3.321 3.313 5.4= 3.448 3.448 (5.4 faster)
INTEGER INDEX 4.11= 2.895 2.873 5.4= 3.271 3.268 (5.4 faster)
FLOATING-POINT 4.11= 5.163 5.156 5.4= 5.020 5.014 (4.11 faster)
all 4 hosts have important services (w3cache, firewall, ircd, etc) and i
cannot turn them off to perform good UFS1/UFS2 tests :(
