Client-Side Performance
Optimizing Rails performance can only take you so far. The client-side plays a big part in how fast a page feels. Here I show many tools that can help make your apps faster than ever.

MiniProfiler
MiniProfiler allows you to see the speed of a request conveniently on the page. It also shows the SQL queries performed and allows you to profile a specific block of code.
