It is the difference between x86_64 and i386, mostly.
Some of it may also be that you are not hitting Mongrel hard enough in
staging. An overloaded Mongrel with default --num-procs setting of
1024 should eventually allocate enough memory for 1024 request handler
threads, which takes even a skeleton Rails app above 60 Mb level.
