Courtenay,
How long do your jobs run to see that type of performance? There seems
to be an initial time penalty when the system builds the file list. I
am running small jobs of 100GB so that probably plays into my initial
times I am seeing. I am getting throughput of about 43MB/sec for my
100GB dataset.
Thank you for your reply.

What do you have the drives attached to? A NetApp? A Linux box?
