A decade ago the standard answer was "run squid" but I guess I missed a mee=
ting.
Looking at the pound web page I see that it isn't going to accelerate the s=
tatic
pages, which squid will do for you.

If Ken Perl (wonderful name -- "know perl") has CPU-intensive mod-perl
applications
that he wants to use clustering to mitigate bottlenecks, instead of
load-balancing,
a loadbalancing front-end might not be the right thing. As long as
the session management
is shared among the servers, load-balancing will work (which has
alkready been said)
if you go really simple and have your cluster all with different
external IP addresses and
use a round-robin DNS, you don't have to worry about session
management sharing as
much because any client will establish an affinity for the server they
are using and won't
switch, in general.
