In the fast test this has no effect on the remote server's tcp, it's
always going to be reno.
Trying to cross-check behavior using our tests...
There isn't a specific reno setting test in flent for tcp_download as
best as I recall, so I was just calling netperf -H wherever -l 60 --
-K reno,reno
then running the flent ping test as previous mentioned.
(flent-fremont.bufferbloat.net and flent-newark both support reno bbr
and cubic, I haven't checked the others)
PS A side note is that we are not fully successfully moving the
inbound bottleneck to cake (at least in the cable case), as we do get
quite a bit of queuing delay even with linux tcp driving the tests.
I'd long written this off as inevitable, due to the bursty cable mac
but I'm grumpy this morning. 0 delay via fq would be better than even
the 15-40ms I'm getting now with linux flows.....
reno bbr cubic
