maybe yes, maybe no... what are the cases where it is needed? The send queue is basically acting as a "shock absorber" for bursty traffic. If the queue is filling up because of a steady traffic rate, then making the queue bigger means it will just take a little longer to fill. The way a longer send queue helps I guess is if the send queue is emptying out before the transmit queue is woken up... with small packets I suppose it doesn't take long for the send queue to drain completely. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
