As it was explained to me 4 years ago, when we first moved to using
2.2 with event MPM, it was marked experimental at that time was only
because it could not handle SSL at all. In the trunk branch, this was
fixed so it would fall back to worker-style MPM when dealing with SSL
connections, and I think this has been backported to 2.2, although I'm
not sure, we still offload SSL to a different apache.

In a word - 'excellent'. We use apache-event as the front-end to all
our web apps, and it mainly serves static files or proxies to the
appropriate backend servers. Our sites aren't super-busy, 1-2 million
hits a day, but with event we have consistently fast connection and
throughput times, the load on the servers barely registers. We've
never had a problem with reliability or speed in the 4 years we've
been running event MPM on our front end proxies.
