What does gstat look like on the server when you are doing this? Also - does a dd locally on the server give the same results? You should get about double that I would estimate locally direct to disk. What about a dd over NFS?
dd-command:
dd if=/dev/zero of=/nfssrv/dd.tst bs=1024 count=1048576
on client: 1073741824 bytes transferred in 24.787112 secs (43318553 bytes/sec) gstat showed approx. 30.000-52.000 KB/s.
on nfs-server: 1073741824 bytes transferred in 23.368815 secs (45947637 bytes/sec) gstat showed approx. 45.000-46.000 KB/s.
The funny thing is that the outputrate fluxuates more dd'ing from the client (remote) and is more consistent dd'ing on the server (locally).
What is the server spending its time doing? (top?)
nfsd.
If you are looking for the best performance, you might try a RAID 0+1 (or 10 possibly) instead of RAID 5.
I chosed raid 5 to maximize space.
What state is nfsd in? Can you send the output of this:
ps -auxw|grep nfsd
while the server is slammed?
I think you are disk bound.. You should not be disk bound at this point with a good RAID controller..
