McGovern" Sender: owner-freebsd-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk 64 ports at 115200 is possible on a Pentium Pro 200... I use the Cyclades 64Ze with the cz driver for FreeBSD (After all, I wrote it). I suggest driver release 1.08, which should be available after I cut it tomorrow :) Up to 256 ports per machine is physically possible (more if you have more PCI slots). Performance may suffer, however, if the lines stay busy. With 256 ports, you'd be looking at a line aggregate of 28800-38400 bps, which isn't good for a 28.8 or 33.6 modem and reasonable compression. Anyhow, using the Cyclades hardware, I loose about 2-3% of the PPro's CPU per port running at 115200. I've yet to try SMP, tho I really want to. Anyhow, to the point of the question. Personally, I like pppd. Our group at Cisco does modem testing all day long, and its been flawless. However, I can also say that many more use the user-land ppp. I guess it'll come down to how hard it is to manage the configuration files, and call setups. -Brian
