Hi,

Some preliminary numbers I have for a 4x SDR IB network, single
disk (RAID 5, 4+1, SAS, 300G 15K disks), single user:

transport        read    write   notes
---------        ----    -----   -----
local            ~254     ~255   for a 100G file, not compensating for 
caching
                                 take them for what their worth :)
nfs              158     76      not gluster, of course!
tcp (ipoib)      171     118     no optimizations
sdp              211     108     no optimizations
sdp              210     128     iot 4, 32MB
verbs            218     150     no optimizations
verbs            220     150     recv/send size 1048675, recv/send-count 16
