Hi!

I think this is a bit Off-Topic, but maybe someone experienced the
same problems using testLVS:

I am using a 3c905 - TX - M on a Pentium 3. I connect a 100MBps
line to it and simulate 100.000 different clients with testLVS.
I'm using the newest kernel and LVS version 1.0.0.

At the moment I start testLVS on the client, I can't use the 
redirector any more. Typing the command "ipvsadm" takes 5 minutes
(really!), but it shows that all 100.000 connections are 
established. The kernel spits warnings that the interrupt is 
very busy. xload shows over 600% load.

Even with a new driver there wasn't big difference.

On the cache however, we experience around 40.000 packets per
second.

This is poor, isn't it?

I didn't think that it's so easy to push a P3 to the limits. 
But I think it isn't the processor, it is the NIC that puts
all the work on the processor. 

Any comments?
