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
