The ones who suffer are the first ones, because their processing is somewhat delayed to 1) let the input batch build up, and 2) complete processing of the batch before pushing results to the next stage. However one should never wait for an input batch to grow; you process whatever your source gives you (one or more packets) by the time you are ready (and if you are slow/overloaded, of course you will get a large backlog at once). Either way, there is no reason to create additional delay on input. cheers luigi _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
