Are you reading and writing the files at the same time? Or are you reading
older files, while writing newer files?
20 clients all write a unique 10GB file (20 x 10GB files), then 20 clients all read the unique 10GB file written previously (20 x 10GB files), then
20 clients all read and write new unique 10GB files *simultaneously* (20 x 10GB files read + 20 x 10GB files written - 40 total) Note that the files being read are the same files from the first write in step 1.

So the second test is
still 20 clients,
but each client is doing a read and write (to different files)?
Correct - as above.
Thanks,
Jake
