I have a kind of interesting question when comes to performance of FreeBSD in different HW. i am not trying to come up with a scientific reason for measuring performance. :-) It is just a curiosity, and of course to see if i understand it and improve performance of my systems. i am running 2 systems at the moment, lets call them S1 and S2, running FreeBSD 9.1-RELEASE-p1 amd64: S1: Intel Core2 Duo E6550 @ 2.33GHz 2GB RAM 500GB disk (not important probably just for reference) S2: 2x Dual-Core AMD Opteron 2216 2.4GHz 14GB Ram 320GB disk (not important probably just for reference) Both the systems are running more or less the same sw, apache, imap server, postfix, and the needed perl/php/python and running very light load. Also both are using a GENERIC kernel and not running X, they are just text based :-) From cpubenchmark.net the cpu performance index are for s1: 1501 and s2: 1518, so very similar. As i felt the AMD system seemed slower when comes to compiling, i just done a "performance test" which was "make buildworld" on both of systems from scratch and the times are: S1: 2h 12m S2: 2h 59m My mind tells me that the S2 system should be faster, just because there are 2 CPU instead 1, or 4 cores and of course more RAM. But the "smaller" Intel seems to beat the crap of the AMD. Is this expected? Should i expect the S2 should be way faster? And just trying to get some advice, is there any tweaks i can do on the S2 system to make it go faster? Like i said i was expecting the S2 to be faster, but of course maybe i am wrong? Any advice/feedback will be appreciated, as i am just trying to understanding and if possible improve performance. Thanks in advance Fred
