I'd say, that rules out the NFS layer. Next is to check your disks. Try read and write operations (and before reading via NFS, do a touch on the testfile to invalidate caches). While the operation is running, run on the server: iostat -yw 1 $disks where disks is the list of physical disks affected (e.g. wd0 wd1 wd2).
