remote message send latencies on low-latency 10Gb/s hardware

Hi,

I wonder if anyone has benchmarked Erlang messaging performance on
low-latency 10Gb setups, such as machines with Solarflare NICs using
OpenOnload talking via Arista 10Gb switches?

Given server to switch to server latencies in the single digit
microseconds, can Erlang remote messaging achieve near this? I guess
a ping-pong of 15ms or so would be the best case (assuming 6ms one-way
latency plus some processing time).

Thanks
B.
