Looks like my dishy upgraded to 4990ce8d-5028-4e51-a015-e9ab1b1ebe1a.uterm.release around 4:30AM CDT this morning. Nathan, did you get a chance to check versions or uptime? Probably worth tracking if we’re looking for performance changes.

Install flent from git... Try a rrul test from any location in the cloud, or at home, or over wifi or 5g to fremont.a.taht.net (one of my measurement servers in the cloud)... or dallas.starlink.taht.net A dishy is available without sqm on between 1AM and 6AM PDT at dishy.taht.net (through an ipv6 wireguard tunnel. (you are d2.taht.net) Moving forward, simplifying things (single flows) and since irtt was not used by our tcp_nup and tcp_ndown tests, a new one "nup" is under development which has a few new things like SCE support. I do have some data on you from today from my cloud, but hey, if you have energy... please try out something like flent -H dishy.taht.net --socket-stats --step-size=.05 -t 'whateverthetestcondidtions" --irtt-sampling-interval 3ms -l 100 rrul and let us know what you find? (the flent-gui can generate plots, you can also output plots from the command line) The tcp RTT plot is my favorite.
