    Hi.

    I'm about to replace our internal nfs- and
    samba-server with a newer Dell 2850 dual nocona @ 3.2
    GHz and 4 GB RAM and 5 SCSI-disks in RAID 5.

    Inspirred by the recent performance-discussions I'd
    like to do my own testing regarding nfs and samba, and
    would like to add some tests like bonnie to aid the
    dissussion on this list and to have some valid points
    in a why-FreeBSD-and-not-Linux discussion at work
    (which is healthy from time to time).

    I haven't installed linux for some years now, and do
    not have a good feeling how the 2.6 kernel does
    regarding smp, disk-io, network etc. compared to
    FreeBSD.

    I want to know, how FreeBSD stacks up regarding
    performance, ease of installation/updating /upgrading
    compared to primarily Linux and to some degree NetBSD.

    My plan is to start with FreeBSD 4.11, reinstall 5.3
    (release), upgrade to 5.3 stable, then move to 6.0
    current, install a linux-distro, and possibly install
    NetBSD 2.0.

    I will apply the following optimizations in
    /etc/make.conf (when applicable):

    march=nocona
    CFLAGS= -O2 -pipe -funroll-loops
    COPTFLAGS= -O2 -pipe -funroll-loops

    HTT will be disabled in BIOS. 4.11 will be the
    i386-port (choosing is not difficult here ;-) and
    UFS1, 5.3 and 6.0 will be the amd64-port and UFS2. The
    amd64-port will also apply to Linux/NetBSD.

    I want to limit my testing to nfs- and
    samba-networking, some web-benchmarking, disk-io and
    network-io. I haven't spent much time on the last two
    items so any small howto, what ports to install,
    pre-written scripts etc. would be appreciated.

    What Linux-distro is most BSD-like? Fumbled with
    Gentoo where portage seems to be a pretty strong tool.
    I'm planning to use ReiserFS.

    regards
    Claus
