We have a webserver setup with 1 Intel Pro/1000 Gigabit Ethernet card. The old server was using around 95mbit/s of traffic or so (sustained rate). We decided to replace that card/machine with something that could handle the high network load. The question would be, What's a good size for NMBCLUSTERS? I want to be -sure- the box does not run out of mbufs during the production phase. The old machine was on a fxp0 driver, mbufs set to 65k due to network overhead. Are there limits to mbufs, as in a size limit? Thanks. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
