There are some more points that made me stick with NetBSD and maybe i'll want to come back to FreeBSD when 5.4 is out. However i think that development for NetBSD will make advances too. What SMP, NetBSD and FreeBSD concerns i have to say that i know much more now than when i wrote to the NetBSD mailing list. I made some assumptions back then which proved to be wrong. Somebody gave me the hint to have a look at "sysstat vmstat" and i saw that the interrupts grew to an high number on disk i/o. It went a little bit smoother without SMP. I couldn't remember that FreeBSD did so, thus i assumed that it performed better. Checking it again exposed that there was almost the same interrupt behaviour.

stheg olloydson wrote: (Sorry about the multiple posts. I somehow sent this without a subject line before.) Never mind. Nobody's perfect. ;) To sum up your problem, you tested "FreeBSD 5.3, NetBSD 2.0, FreeBSD 4.11 and an elder version of the Knoppix (Linux 2.4) CD" and found that FreeBSD 4.11RC2 had the best ping responses from that group. What you want to know is why FBSD 5.3 doesn't respond as well as 4.11RC2. Is this correct? You got me right. Assuming that it is, the answer is that 5.3 is the first stable release of the 5.x branch. One of the 5.x branch's main purposes is to make FBSD much more scalable in terms SMP support. Doing this requires removing the Giant lock. It had been hoped that the removal process would be finished in time for 5.3. Unfortunately, as often happens in a volunteer project delays occurred for various reasons, that was not the case. The incomplete removal meant that not all subsystems could be optimized properly. One of those subsystems is networking. This is not as bad as it sounds because while 5.3's network performance is not as good as 4.11RC2, it is no worse that of NBSD 2.0 or any Linux distro. Also, the optimization has already begun on networking and 5.4 should be _at least_ as good as 4.x. Also, as you saw yourself, using an SMP kernel in FBSD 5.3 doesn't cause a performance hit in networking but it does in NBSD 2.0. So your choices seem to be use 4.11RC2 (full release due shortly) to get the best network response, 5.3 to get as good performance as NBSD 2.0 but with SMP, or use NBSD 2.0 to get as good perfomance as 5.3 but without SMP. Of course, you can wait until NBSD (your prefered OS) performs as well as FBSD, but that may be a lnng time.:) Just a few day ago i installed NetBSD 2.0 to make a final stroke to my decision as i got this computer on the 16. of november.

What "puzzles" me is that they call 5.x the "production version", even though they seem to know its not there yet. So (sadly), you can't run the fastest version on the fastest hardware. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
