I have a few machines in network. I'm using FreeBSD as my NAT/firewall. The NIC's in the FreeBSD box are 3c509B's. It's a P90 with 32 MB of RAM, and at least double of swap. Not running any caching/proxy servers, unless you consider NAT as a proxy. When exchanging files between my FreeBSD box and others on the network, and no Internet traffic, at maximum I've seen ~ 250 KB/s (not quite 2 Mb/s) transfer rates. When I get Internet traffic, the transfer rate goes way down if I also try to transfer files, and I get strange behaviour from the network. Traffic happens in bursts, which seem usually (but not always) disrupted by collisions, and usually there's a fairly long pause (a few seconds) before traffic starts again. I would think part of it has to do with the system being dual-homed, with two 509's, but I'm sure there has to be something to do to improve performance somehow. Does anyone know where I should look to get my box to react a little more sanely? If there's anything else you want to know just ask :) Thanks!
