[AusNOG] Microtik bgp issues

Wed Nov 5 12:15:07 EST 2014

I have that same issue on the CCR1009 - can't push more than 700mbps on
a single TCP stream. I can get it to 900 if I disable ip conntrack and
filtering entirely, but that isn't really an option unless I want more
hardware to offload that job.

 We ran to the sounds of thunder.
We danced among the lightning bolts,
 and tore the world asunder
