Re: [LARTC] P2P shaping working

Does anyone have a clue on why's this happening? Thanks to everyone that help me, I really appreciate it. Shaping upload will affect bittorrent downloads as it it part of the protocol for peers to favour the connections that are giving them the highest rates. That may not be the only thing though, if you are marking with ipp2p then the acks for the download will be queued with the upload traffic - this happens with the ones that get piggybacked anyway, but I let empty bt acks have priority over those. It would help if you make the bt queue fairly short. Andy. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Guess 2: You are dropping incoming packets, causing resends. Guess 3: The outbound queue(s) are full so the ACK can't be sent "NOW, DAMNIT"! Guess 4: You have not tweaked /etc/sysctl.conf and run sysctl, so the internal buffers are too small. Guess 5: Your CPU is overloaded by the queuing. Guess 6: Your IMQ is misconfigured. AFAIC, ACK and window size are the most important issues. You must prioritize the ACKs not associated with file sharing and delay the hell out of those that are associated with file sharing. -- gypsy ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
