Right – time to ditch flaky Apache modules and go and play with the real stuff. Well, I would, except that OS X ipfw doesn’t support the pipe directive (no dummynet), so instead the rather nifty throttled comes to the rescue, and with a couple of those going external web and email are now slowed so that the asymmetric line I have shouldn’t get saturated, and all those helpful ACK’s can still make it through.
Hopefully.
