I recently tested a Compaq DL380, 733Mhz processor, 512meg ram with two fiber 64-bit Intel Pro 1000's. The system (4.8-R) forwarded 500 megabits at about 20% idle with IPFilter loaded but with no rules. The system uses a ServerWorks chipset and has several 64-bit pci slots. I used netperf on several systems on either side of the firewall. In the next week or so I'll be testing two Pentium 4 2.4 gig systems with ServerWorks chipsets using a much larger cluster of load applying systems. I'll post those results.
When I tested the same configuration on a Compaq 1850R (450Mhz, i440BX, 32-bit PCI) I could only muster about 250-270 megabits of traffic. I figured the PCI bus was the limiting factor and stepped up to the DL380.
Previously I've forwarded 50,000 packets per second on a Celeron 900Mhz, Intel 810 chipset, 32-bit PCI (4.4-R) system with IPFilter loaded and IIRC 150 rules in effect. The system used Intel PRO/100S dual port server adapters. I used ping -f for those tests.
I have access to about 25-30 systems to apply load with so if anyone wants something specific tested I might be able to work it into my schedule.
