Hi,
I've got a 100Mbit NIC and used iperf and netperf to
test them. The measured throughput is around 92Mbit.
My question is what causes the degrade in
performance??
Overhead in packets?? CPU clock speed(My desktop uses
P3-500MHz)??
Best,
William

Hi,
That's normal.
Every packet that you send, has a tcp-header. So you can only send
92Mbit of data. If you used udp, you would get a throughput around
94Mbit.
Best,
Wouter
