Good News From 10Gbit Land

by DropTableFoxes

Previously in 10Gbit Land…

Browsing through Mikrotik’s RouterOS changelog I noticed something.

6.42rc6 includes this (Yes, this was a while ago - I’ve been busy):

*) crs317 - improved transmit performance between 10G and 1G ports;

Is this what I was after? Let’s try it out…

iperf Done.

Still a few (hundred) megabits short, and a rather high retry count, but certainly better than what we were seeing before - so I’m happy to go back to bridging rather than routing.
