What sort of CPU power is required for a director machine?
a 400MHz machine can saturate a 100Mbps ethernet link. How
fat is your pipe?
It's certainly more than a firewall since there's routing
(and encapsulation) involved.
routing and encapsulation are relatively cheap (although I
don't know what "relatively" is). The slow step is (or was
last time I looked) assembling the packet in the buffer, not
constructing the parts that will make the final packet.
Can you change a couple of your LVS-DR realservers over to
LVS-Tun and see if there's any effect? You could eventually
have them all running LVS-Tun in your current site before
you commit to the real off-site LVS-Tun setup.
Do you realise with the standard LVS-Tun setup that you
can't do health checking on the realservers? You'll need to
add a two way link between the realservers and the director.
