Hey Baptiste, Awesome test! Thanks for reporting the results. On Sat, May 13, 2017 at 9:37 AM, Baptiste Jonglez wrote: > Using iperf (TCP mode) over the wireguard interface, performance was > around 1.6 Gbit/s. In bidirectional mode (iperf -d), performance was >

Performance of Wireguard on Infiniband 40G

Hi, Just for information, I did a quick test of Wireguard over a 40G Infiniband network, between two machines with a Xeon E5520. Using iperf (TCP mode) over the wireguard interface, performance was around 1.6 Gbit/s. In bidirectional mode (iperf -d), performance was 700 Mbit/s + 800 Mbit/s.
