Post your performance results
I thought it might be interesting to see what kind of performance everyone is getting with IO Meter so that we can compare what we're getting. So I thought we could all post our results in this thread...

These seem to be consistent with others in that enabling JF helps writes but slows reads. The interesting result is 'NV Jumbo On, via Switch, NIC @9k' which considering the switch is not supposed to support JF gives the same results as direct. Furthermore I can surf the net just as quickly it seems via my 100BaseT Draytek ADSL router. Since I have done the majority of the copying to the NV I think I will stick with JF off for the improved read, but it might be worthwhile enabling JF as and when I need to do any more bulk copying.
I have two HGST T7K250 250GB HDDs on order to bring the RAID upto 1TB, as well as 1GB stick of Patriot RAM, so I'll post back with updated performance tests once these are installed.
