I don't believe it. This must be a wrong setup or a damaged hardware
component.
Its impossible that a lousy Celeron is faster then a P3. Sorry
pal, such is
life.

Never tried but this is not the point anyway.
You said it.

I assume you're using LVS_DR seeing your setup. But why are you
using
2 NICs?
Not 2 NICs. I only want to describe the problem in more clear way.
To avoid the arp-problem?
No. we use ipchains.
So the DGW for the all RS is the LB?
The RS is LB.
With this setup the replies must travel back through the director
and
then you have the performance problems of LVS_NAT. Please change
the
setup to the LVS_DR setup depicted in the howto. And then we might
check out your problem again.
I am very sure that i setup to LVS_DR. I know the difference
betwwen LVS_DR and LVS_NAT.

It's impossible IMHO. But YMMV,
