Hi! I have a problem since I changed the NIC of my server to a <RealTek 8169S Single-chip Gigabit Ethernet> driver re. I encounter a lots of NFS server not responding from any clients as soon as the load on the network increase. I had to do an horrible hack: I added the following script on the server crontab every 2 minutes: #!/bin/sh /sbin/ifconfig re0 mtu 1490 /bin/sleep 15 /sbin/ifconfig re0 mtu 1500 The performances are poor because after between 1 or 2 minutes, the NFS server is not responding but it is usable. Any idea besides changing the NIC? Thanks Phil.
