I did some bursts test with htb. You can see on some of the graphs that if there is an other tcp stream, htb reacts very fast. But this only for outoing packets and measered on the loopback interface. So the problem is not htb, but application, routers, modems, ... http://docum.org/stef.coene/qos/tests/htb/burst/ Stef -- stef.coene@xxxxxxxxx "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.openprojects.net _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
