yes, had we found a way to support windows, we could have (and could still do) better. Regrettably we never did find a way - or funding - to drive tests through windows (wsl works). I still (as do many other folk in the Bufferbloat world) rely on flent to drive all kinds of tests. nothing compares to flent's ability to compare multiple network tests in so many ways.
