At the moment Mongrel can't use the copy-on-write optimizations provided 
by Ruby Enterprise Edition.

As for Apache, it's possible to tweak it to lower its memory usage to 
levels comparable to Nginx. The key lies in disabling all modules that 
you don't need, and using the worker MPM instead of the default prefork 
MPM, with settings comparable to Nginx's. The resulting memory usage is 
described at http://www.rubyenterpriseedition.com/comparisons.html.
