I suspect there are interrupt aggregations on more than just Linux. I would expect every *nix and even Windows to have interrupt aggregation/coalescing. I would expect it to delay notification to the host that the packet has arrived by anywhere between 5 and 20 microseconds, but that is an off-the-cuff estimate. rick jones -- Process shall set you free from the need for rational thought. these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
