Question

Page loading on my development machine has fallen through the floor since upgrading to Rails 3.1 and enabling the asset pipeline.

I used to see page loads taking 1 or 2 seconds but they’re now regularly over 10s (on localhost).

This is starting to really hamper development speed, is there a way to accelerate things?

Answer 1

10 seconds?! That’s pretty slow indeed…

First of all, if enabling the asset pipeline means that you compress the assets in development mode, stop doing it:

# config/environments/development.rb
config.assets.compress = false

Then bear up until the Rails 3.2.0 release. The changelog may interest you:

Speed up development by only reloading classes if dependencies files changed. This can be turned off by setting config.reload_classes_only_on_change to false. José Valim

Finally can you post a sample of your logs + your config please?
