Thanks for your reply! For results above, we use default mount options on OpenBSD NFS client (v3, udp, timeo=100) and Linux NFS client (tcp, v3). We tested now with "udp" option on Linux NFS client on your test server (with OpenBSD 4.5) and performances are... good : ~25 Mbit/s. We downgrade to OpenBSD 4.4, again poor performances (~400 Kbit/s), even with "udp" option. Then we will now upgrade to OpenBSD 4.5 on your production server to confirm if OpenBSD 4.5 NFS server and Linux NFS client with "udp" is the magic duo.
