This is consistent with the situation where packets are received at a rate faster than they are being consumed. No matter how big your queue is, it's going to fill up eventually and overflow, and all you're doing by increasing the queue length is adding latency to all of those packets that you do process. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
