Greetings

Am setting up an freebsd machine to do traffic-shaping on some customers. 
The situation is following:

Am feeding a site with 4mbps of internetcapacity

- Have approx 230 user incoming via catv 

- Approx 100 user attached directly via Ethernet

Hardware = Dual PPro 200Mhz, 128 RAM, 1 Intel EtherExpress NIC & 1 Realtek 8139

The catv customers should have 3.5 mbps and the rest should have 500kbps.
Have tested dummynet with my workstation and pico bsd, it worked well.
But what considerations should be taken regarding hardware and queue sizes
when over 300 users are flowing through the bridge? What should be considered
as "normal". Trial and error is an option of course but this would generate
a lot of angry phonecalls to me ;-)

TIA!

-Rickard
