In that sense, the config looks OK to me. However, I am a bit skeptic on the NFS mount in general, I know several users have reported problems of various kinds with such configs. Maybe many more happily use the same ;)
The big problem with NFS is that the spec requires tha the NFS server receiving the message have the data on durable media that will survive a reboot before it considers the write complete.
This means that unless you have a very expensive NFS server that has non-volitile ram tp ise as a wrote cache (and you don't overrun that cache), each write to NFS requires that the NFS server does a fsync.
This can cripple your write performance (with a fsync for every write, a 7200 rpm drive can write ~160 messages/sec, a 15K rpm drive can do ~300 messages/sec)
