What's everyone favorite way to do this these days? I have nginx with 4 mongrel processes now which is great for the performance of this 1 rails app I'm running. But to add another rails app to the box would require 4 more mongrels. Each mongrel takes like 20 MB of ram for the ruby VM. Is there a way to run 4 mongrels total but have each mongrel switch on-the-fly to the needed rails app? That way I could run X # of rails apps but always keep the # of mongrels steady at 4. Or, is it better to use fastcgi and forget about mongrels if I want multiple rails apps? Thanks.
