Is there a direct correlation on site speed with the number of namespaces / routes in the routes.rb file of a Rails Application?
I am handling a fairly large application with more than 30 disparate models/entities and most of these resources have their own routes.
I don't have a citation† but DHH recently said that 37signals' Highrise application has thousands of routes, so it is possible to scale the routes if you have a big enough box to run your application on.
† I think it may have been during his recent RailsConf keynote, when he was talking about the new router API in Rails 3.
the number of routes will affect the memory overhead - it's why rails no longer defines formatted routes out the box: http://ryandaigle.com/articles/2008/11/27/what-s-new-in-edge-rails-no-more-formatted-routes
It's not unusual to have 30 or so routes though
As for whether or not this will affect the speed of your app, it's difficult to say - are you using metric-fu or anything like that?
