Hi,

I have problem with routes. It’s the big one (over 50 resources) and  
starting an app is a pain - 3-4 seconds. I’ve added :only and :except  
options where I could and it’s better than at the beginning but  
still… slow.

I use passenger to deploy apps, so fast boot is important. I thought  
that most of the routes are not used often anyway (especially those  
from admin/) and in most cases while instance is running (and while  
passenger stops app after 5 minute idle time) most of the routes are  
not used… Generation on demand would fix this problem.

For example: I call user\_path(@user) and it doesn’t exist so it’s  
generated and is available with next requests.

Is this doable? Or maybe there is some plugin which makes the trick?
