How can I improve the performance of my Rails application with gems?
You can start by profiling your application to identify slow gems. Tools like Bullet and Rack Mini Profiler can help.
What are some common gems that can cause performance issues?
Common gems that may slow down your app include ActiveRecord, Paperclip, and Devise, especially if not configured properly.
Are there any alternatives to these gems that are more performance-friendly?
Yes, for file uploads, consider using Shrine instead of Paperclip. For authentication, you might try Authlogic.
How can I monitor the performance of my Rails application over time?
You can use tools like New Relic or Skylight to monitor performance metrics and get insights into your application's behavior.
