Wow, I see flent’s combination plots are handy though.

Stuff to sort in irtt also. Merely setting the source IP of an outgoing packet doubles allocated heap when it calls into x/net code. Super.

Ok, here’s a quick veth try but I gotta get to sleep so I’m not investigating much ’til later. I wonder if 4.9.0-4 is enough:

# I’ve been a bad boy and did sudo make install in iproute2-cake-next
export TC=/sbin/tc
