Subject: netperf3 results on 2.5.25 kernel

I did a comparison test on 2.4.17, 2.5.25 stock kernels and on 2.5.25
with NAPI enabled e1000 driver using netperf3, tcp_stream 1 adapter
test using UNI kernels. The test setup/results can be found at:

On which machine(s) do you actually test the kernels? Source machine?
Destination machine? Or both?

On both the server and the client, I used the respective kernels.
However I used the cpu usage from the server since my objective
is to stress the server in this test.

I am just catching up with my mail. Sorry about that. I don't think
I understand your question completely. Let me answer, if I don't make
it clear ask me again.

The client and the server systems have the same level kernels. The CPU
utilization collected at server end is used to derive the throughput
scaled to CPU. The throughput for tcp_stream reflects the rate of
transmits at the client and the rate of receives at the server.
