rails 3.2.1 very slow in development mode

Question

Since i upgrade my app on my development server, the request are terribly slow. Event if the log seems to render quite quickly, it take 10-15 second for the loading to be complete (event if the page is already fully loaded)

My configuration :

Rails 3.2.1
Ruby 1.9.3-p125 (rvm)
Standalone Passenger (3.0.11)

I do not have this kind of issue on my development machine, so i guess the problem is not coming from my application

After some search, it occurs that application.js is not served properly (incomplete file) - does this sound familiar to anybody? — AkyRhO, Feb 23 '12 at 11:14
it has to be something with 'rails asset pipeline' - google that, also did you checked that http://stackoverflow.com/questions/6826154/rails-3-1rc4-asset-pipeline-broke-after-ruby-update-how-to-re-activate-configur — mpapis, Feb 23 '12 at 13:05
Are application assets being served from the server? Are logs indicating that js/css/images being served? — Kunday, Mar 09 '12 at 06:01

I had a very similar problem. Found this question ( Slow assets ruby 1.9.3, macos, rails 3.2 ) which helped me discover it was chrome where the problem was occurring. Still don't know why, or how to fix it.

In my case it was Rails Panel extension that was slowing Chrome. I just disabled it and it the app became 3 times faster.
