I am very interested to see the memory usage. With mod_perl, you pre-loaded a lot of your modules in the httpd.conf file, and Apache loads them once and shares them across all processes saving memory. With Rails that could give large memory savings, and memory is the major pain point of getting more than one or two Rails apps up and running on the same server as I understand it.
