9.2 64Bit + RAID = very slow NFS transfer and high load??

Hello!
Situation: a dual opteron 9.2 server with SATA-RAID (3Ware - driver:
3w-9xxx) and a dual opteron 9.0 accessing the RAID with NFS. I'm
moving data from the "client" (9.0) to the server with mv command.
Load on client is nothing. Load on server is 2.5-3 and yet there is
nothing running there; Top has nfsd process at the top with 1-2 % CPU.
Computers are connected via Gigabit ethernet. Data transfer rate is
very slow: 2.2Mb/s!
The problem is not at the client end as we had the same kind of
results transferring data from another (RH) server to the new SuSE
9.2.
Installed kernel is 2.6.8-24.11 (default SMP-kernel from SuSE). The
RAID driver is also from SuSE 9.2 (I could not find information about
which.
Any ideas? Any pointers to check? We really do not have any idea what
is slowing down the server?
