Among the requests, the usual ones:

Request response duration
Execution profile of flow (path taken, time in methods)
SQL Queries made
Analyze and Identify performance bottlenecks - in-memory, sql query exec

Warning! This is not a full-blown tutorial, rather a quick step-by-step intro on what you have to do to run Rails on your Mac, if you are a noobie who just heard of Rails and wants to have it running on his computer ASAP:
