We evaluated Ethernet performance using the NTttcp tool from Microsoft's Windows DDK. The docs say this program "provides the customer with a multi-threaded, asynchronous performance benchmark for measuring achievable data transfer rate."
We used the following command line options on the server machine:
ntttcps -m 4,0,192.168.1.25 -a..and the same basic thing on each of our test systems acting as clients:
ntttcpr -m 4,0,192.168.1.25 -aOur server was a Windows XP Pro system based on Asus's P5WD2 Premium motherboard with a Pentium 4 3.4GHz Extreme Edition (800MHz front-side bus, Hyper-Threading enabled) and PCI Express-attached Gigabit Ethernet. A crossover CAT6 cable was used to connect the server to each system.
The nForce4 boards were tested with the NVIDIA Firewall and Jumbo Frames disabled.
As expected, the KA1 MVP's 10/100 Fast Ethernet controller doesn't come close to matching the competition's throughput. The chip's high CPU utilization is even more disappointing and certainly unjustified given its slow transfer rate.
