        :) What to say, you see how many changes adds LVS to the masq
code in 2.2 and always by trying to keep the masq code when the LVS
is not compiled. May be this is the only change that touches the
2.2 masquerade without preserving it for !LVS. For good.

        The same is here. I didn't found today a way to flood my cluster
properly. I feel a little difference but for now this is only a feeling :)
I can't fully load my director. Any difference will be visible with
long packets.

        Yes, may be results from netpipe will be useful.
