Sorry I know this is a generic question, I’ll try to provide as much detail as possible

I am running Bitnami Rubystack (3.2.7) on Amazon EC2 Medium instance. and some aspects of Rails are extremely slow, here are some of them:

  • when logging in (I am using devise gem), if you provide an invalid password, it would take a long time to tell you that the password is invalid.
  • Sign Up process takes extremely long, responds after about 2 minutes (when all it has to do is run a couple of queries agains the db?)
  • File uploads (on carrierwave) are so slow they are practically not working. (files are going to S3 via Fog on CarrierWave).

The code in the above instances is pretty straight forward and I don’t see anything obviously wrong. In fact, most of the work gets performed by the gems (e.g. devise handles registrations and logins). any help would be greatly appreciated.

    Try to use a analytics tool, like New Relic

    This will help you locate te slowest code and/or the slowest db query


    EDIT

    On the comments below you have mentioned that you are using devise 0.5.8, this is very bad, considering that devise is, today, at version 2.1.2

    Please update your devise and keep me posted.

    NEW EDIT

    Since the devise version is not the problem you could look into the views.

    In the views check for http requests that could be inserted on a single request or a async request.

    For instance Google Analytics.

    If the load of their javascript files are blocking your view to load maybe putting them on head or making them async could help
