Further steps that don't involve increasing the

include lighttpd and/or nginx. At some point you're going to need
something capable of interpreting PHP but if you can make as many
requests as possible avoid getting that far, serving things out of
cache, sending static requests to lighttd/nginx etc., then you get
further.

From personal experience, using FastCGI + Apache's threaded worker is
"enough" memory wise. It might be a good intermediary step as it won't
require configuring a new httpd.
