Issue #2428 has been updated by Francois Tigeot.

Status changed from New to Closed
% Done changed from 0 to 100

And this is actually an iperf feature: default udp stream tests are limited to 1Mb/s

More than 800 Mb/s transfer speeds are possible on most ethernet interfaces without needing to do much tuning. Closing.
