I suspect I'm having performance issues because of network speeds. Supposedly I have 10gbit connections on all my NAS devices, however, it seems to me that the fastest I can write is 1Gbit. When I'm copying very large files, etc, I see 'D' as the cp waits to I/O, but when I go the gluster servers, I don't see glusterfsd waiting (D) to write to the bricks themselves. I have 4 nodes, each with 10Gbit connection, each has 2 Areca RAID controllers with 12 disk raid5, and the 2 controllers stripped into 1 large volume. Pretty sure there's plenty of i/o left on the bricks themselves.
Is it possible that "one big file" isn't the right test... should I try 20 big files, and see how saturated my network can get?
