Is active-active LVS really capable of doubling theoretical bandwidth?

Horms would be the final word on the matter, but he seems to 
be busy (hasn't popped up on the mailing list for a few 
weeks). I haven't read the Saru docs for a couple of years 
and you seem to have read them thoroughly and I assume 
you've got it right.

n active directors can handle n times the bandwidth, but you 
have to send it to them. You'll need 10GigE (or something 
like that) in front of them.

I didn't know that the directors had iptables rules infront 
of them to divide the work load. One of the requirements is 
to load balance and handle failover, so there must be at 
least two directors capable of handling any particular 
stream of traffic.
