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
