[Gluster-users] A year's worth of Gluster

I have a similar system with 4 nodes and 2 bricks per node, where 
each brick is a single large filesystem (4TB x 24 RAID 6). The
computers are all on QDR Infinband with Gluster using IPOIB. I
have a cluster of Infiniband clients that access the data on the
servers. I can only get about 1.0 to 1.2 GB/s throughput with my
system though. Can you tell us the peak throughput that you are
getting. I just don’t have a sense of what I should expect from 
my system. A similar Luster setup could achieve 2-3 GB/s, which
I attributed to the fact that it didn’t use IPOIB, but instead used
RDMA. I’d really like to know if I am wrong here and there is 
some configuration I can tweak to make things faster.
