Hi, Thanks to everyone who responded, including Michael Kiernan, Brett Lymn, AP, etc. I had a number of suggestions such as: Option 1 use UDP and NFS Version 2 abcd:/db2/temp/share /db2/temp/share nfs rw,bg,vers=2,proto=udp Option 2 reduce the write packets size std=32k abcd:/db2/temp/share /db2/temp/share nfs rw,bg,wsize=8192 Check out all the options in man page $ man mount_ufs AND The best policy in this situation is to try all combinations and see which works best for your server/network/client So: proto=tcp,vers=3,rsize=1024,wsize=1024 proto=tcp,vers=3,rsize=32768,wsize=32768 (try also proto=udp if the network path is short and reliable) maybe also try: vers=2,rsize=1024,wsize=1024 benchmark with something like: timex dd if=/dev/zero of=/nfsmnt/out bs=1024k count=1024 In the end, I created a cache-fs which seems to have gone some way towards helping the situation.

The mount line in /etc/mnttab is as follows: abcd:/db2/temp/share /db2/temp/share nfs rw,bg,dev=4712305 1042098734 I have 2 other read only filesystems that are also mounted from server abcd that are performing fine. When I copy data to the one mounted rw, the whole server slows down. Does anyone have any suggestions or ideas? Do I need to specify particular parameters when doing the mount? I will summarise.
