Hi Toke, thanks for that, I’m finally getting around to using flent from source now, and saw the new plots: tcp_cwnd, tcp_rtt and tcp_rtt_cdf- then figured out they only work when the test is run with the —socket-stats flag. :)

They shouldn’t otherwise affect the results, right? Because I’d basically enable this for all of my flent runs.

Preliminarily, I _am_ seeing differences within TCP flows as the configuration is changed on my OM2P-HS / LEDE setup. There are some surprises, at least for me, but I’ll save the details until I post my second round of results because they require a lot of context, but hopefully these stats help give more insight into what’s going on. Thanks!
