I think the proxy cache is more theory than reality especially given
that any site that is SSL will not be cached by a proxy. That said, I
think the new pristine store offers us abilities in the future to not
download files we already have in the cache and the Serf style will
work much better with that concept (which of course is just another
cache).

I could be wrong, but I think all of the cases about the CPU are
related to WC-NG and not Serf. The high CPU is also seen with Neon.
This is more of a 1.7 vs 1.6 issue.
