Apparently, my cable modem is introducing about 550ms of buffer bloat (worst case scenario) in the upload direction. This was tested without the router in place.
A sensible thing to do is to move the bottleneck to the WAN-interface and then specify a suitable scheduling algorithm. Since my upload is pretty stable at 3.5 megabit/second, I was thinking on using RED.
But since I’ve got no idea how to configure this, I was wondering whether someone has an example config to share?
Thanks,
Jeroen
