Bad write performance

[ Edited ]



On a 1Gbps link I get only about 30 MBps (240 Mbps) from my NFS export on NetApp Release 8.3.2P2.

But if I do 4 mounts and write on them in parallel, then I get about 100 MBps (800 Mbps), which is much more acceptable regarding my hardware.


Is there any way to get the same speed with a single mount?


Thank you.


PS: I saw NFS performance is limited without CPU/Memory/Disk bottleneck on clustered Data ONTAP 8.x system, but I cannot believe there is no other way.
