Dave,

= Did you leave your ingress at 0?

How about ack filtering and overhead on egress? Do you mind shari= ng your tc qdisc commands?

Have you run the auto rate script?

I hadn't looked
at the native performance in a while which is markedly better than it
was a few months ago, at least for this quick test run.

If anyone can make sense of these... for the first 1/3 of the trace
throughput is low and RTTs are *NICE*,
the second looks like a sat switch - still nice... then another sat
switch where I get full upload throughput
and the latency grows significantly.

If anyone is into packet captures:

http://www.taht.net/~d/starlink-1-auto.cap # starlink = through their wifi
http://www.taht.net/~d/starlink-1-cake6.cap # starlin= k through their
wifi, with cake bandwidth 6mbit on mine
