Ab
From Wasya Wiki
Apache bench
Suppose we want to see how fast Yahoo can handle 100 requests, with a maximum of 10 requests running concurrently:
ab -n 100 -c 10 http://www.yahoo.com/
Copy-paste the session cookie from chrome debugger into curl. This way you won't have to write any code scaffolding to permit a session.
ab -c 10 -n 100 -C "_session_id=<id>; _smt_rails_session=<session>" http://localhost:3000/job_numbers
