Hi,

according to benchmarks published in ix (ix is a german unix focused 
computer magazine) the 2.2.x kernels of linux are less than about 10 - 15%=
 
less scalable on multiple cpu=B4s (tested on 4 and 8 way x86 cpu machines)=
 
than solaris and SCO=B4s unixes, I will check for the exact numbers, these=
 tests 
are based on benchmarks like the spec suite. I can remember an article in 
daemonnews that said, FreeBSD was about 19% faster than Linux (do not 
know which kernel freeBSD was compared to and the testsuite). The way I 
interpreted that (may be wrong), the gap between commercial unixes and 
FreeBSD/Linux is only marginal.
