Hi I did some speed tests and I'd like to hear some reaction about this. Linux FreeBSD dd 2.61 4.95 dd if=/dev/zero of=/test bs=1024 count=5000 gzip 12.50 11.01 gzip -9 test gunzip 3.86 8.12 sync 4.21 0.9 -> So it seems FreeBSD writes everything to disk directly?! WHY? This makes FreeBSD much slower! unzips 4.45 41.92 decompress the sendmail distr compil 353.79 371.87 compile sendmail (makesendmail) Yes, I used the same (slow) disk on my i486 But I was really surprised discovering that FreeBSD is much slower in disk access than Linux, so why is the filesystem called FFS (fast-filesystem?!) ;-) But, my main question -> I think FreeBSD is that slow because it writes everything to disk directly, without a good cache. Why is this like it is? This does not make FreeBSD very attractive for me to use as a fileserver (nfs or samba) or e.g. a mail server. -= Paul =-
