Erik,
What version of glusterfs are you using?

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?
