How do I stop rails from regenerating routes on every request?

I am working on a pretty large rails project with a lot of routes. If rails is in development mode the app runs extremely slowly because it has to generate the routes repeatedly. I've tested this a couple of times by removing most of the routes and our app is nearly instant in bringing up our pag开发者_JAVA百科es rather than the 10 or so seconds it usually takes. What I'm trying to find out is how I can stop rails from regenerating the routes on every request when in development mode. Is there a way to cache it or just stop it from regenerating?

I wouldn't advise it, but set cache_classes to true in your config. You'll have to restart the server every time you want to test a code change though.

Did you get anywhere with this?

I'm a little late to the party, and I don't have a direct answer for stopping the regeneration of routes, but would you accept speeding up other parts of the development environment as a compromise? If so, it's worth checking out the Rails Development Boost gem. I've had some great speed increases from there.
