I finally figured out what in emule was ruining my network. I tried everything and nothing worked. I was always getting timeouts. Until i went into the extended settings in emule and changed connections per 5 seconds to 5 from the default of 20. Miracle. It now works great. So apparently lots of connection attempts in a few seconds is an effective way of starving all other machines behind a linux gateway even if you''re using SFQ. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I wonder how this can be. Some tcp connection specialists out here? Is it so that after a long time the connections are fair distributed or is there always a starvation of the other connections?

If you open lots of connections then, it means every connection will get worse. If this is the problem, this will not happen with ESFQ, afaik. --- John Bäckstrand _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I can reproduce this just increasing the number of connections per 5 seconds to 20 again. The effect is imediate. I get connection timeouts in HTTP (more apparent, i''m sure other protocols suffer too) and have to reload a series of times before the connection "goes" and even then it then fails for some other elements in the page. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
