Hi.

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.
