<p class="MsoNormal"><i>Supposedly</i> 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.<o:p></o:p></p>

the right test… should I try 20 big files, and see how
saturated my network can get?<o:p></o:p></p>
