Hi all,

I placed here:
the results I collected using 2 Mellanox ConnectX-5 linked by 100Gbps
fiber cable.

The results are not too much different from those at 10gpbs
(http://zeromq.org/results:10gbe-tests-v432)... the difference in TCP
throughput is that
 - even using 100kB-long messages we still cannot saturate the link
 - latency is very much improved for messages > 10kB long

Hopefully we will be able to improve performances in the future to
improve these benchmarks...

Do you have a test which can show first that you can saturate the 100gbps

Like an iperf or a simple wget test?
