Hello, Sum-up: -------
We try to use NFS server in different machines and network environments and we have very poor performances. Our main test is creating a big tar archive on local NFS server. With NFS server on OpenBSD 4.5: speed result is about 500 Kbit/s for NFS Linux clients, and about 2 Mbit/s for NFS OpenBSD clients. Details: -------- Two years ago we deploy a NFS server with OpenBSD 4.0 on DELL PowerEdge 1900 server (RAID 5 with PERC 5/i on SCSI disks, Broadcom BCM5708 network card, see dmesg in attachment). NFS clients are machines on the same local network (Linux, SunOS, etc.). No problem was reported. We upgrade to 4.1, all was always right. But after upgrading to 4.2, users begin to be unhappy during big files transfers or big tarball creations (note we are not really sure they did these operations before). Then we try to optimize NFS (trying differents options - tcp/udp for example - for clients or increasing nfsd number for server) and change hardware (use another network card, another wires, another switches). Always very slow... while there are no problem with SunOS or Linux NFS servers. Moreover connections to OpenBSD NFS server are often locked with classical messages: nfs: server FOO not responding, still trying nfs: server FOO OK During the creation of a big tarball, nfsd process are often in run state "D" (disk wait). We verify disk performances but they are pretty good in local filesystem. We upgrade to 4.3. Same behaviour. 4.4 too. In another office, we try with a different machine (see dmesg in attachment) with OpenBSD 4.5 on a new network environment. It's a little better, but too slow again. Example when creating a big tar archive. With OpenBSD NFS client, it's not too bad: obsd-nfs-client:/mnt/nfs% du -sh test/ 1.5G obsd-nfs-client:/mnt/nfs% tar cf test.tar test/ ....during about 1.5 hours... With Linux NFS client, it's too slow: linux-nfs-client:/mnt/nfs% du -sh test/ 1.5G linux-nfs-client:/mnt/nfs% tar cf test.tar test/ ....during about 7 hours... We are aware some sysadmins use OpenBSD NFS server with success (we find happy users in openbsd-misc archives). But we don't. Have you ideas for us ?
