Description

Using net/iperf to measure UDP throughput performance on various
ethernet interface, I constantly get values of 1.05 Mb/s on recent
DragonFly 3.1 systems

Tested both with IPv4 and IPv6
Tested with 1Gb/s and 10Gb/s interfaces (em, re and ixgbe drivers)

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.
