Best way to stress test a rails web app? [closed]

Are there any good (preferably free) tools out there?

Can they give accurate estimates that reflect production results when the app goes live?

Stress test usually means testing the whole stack of software that delivers the information and is not necessarily bounded to a language. Another term would be performance testing. And You may also want to try functional web testing tools to test the most paths. Want you want is quite large. – Manteau 23/11, 2008 at 0:6

This is definitely not a free solution, but webmetrics will get the job done. (As well as any website monitoring company in general). They give thorough reports on your web site's performance, and when you schedule load tests you can specify how much load you want to simulate (e.g. simulate 2000 users using my site at once).

I don't think it will break it down and tell you your CPU usage and such, as they stress your website from their servers.

I would personally go with Apache Bench http://httpd.apache.org/docs/2.0/programs/ab.html

It's free, straight forward to use and lightweight.

If you are looking for a something a little more robust then I think Apache JMeter might be worth looking at. http://jmeter.apache.org/. Again, it's free, a bit of a learning curve and has a GUI so a little heavier.

After a Google search for Webload, I came upon this site: radview.com. They charge you a license fee and I couldn't find the open source link. – Selwyn 7/8, 2012 at 19:11

Yeah, not only is it not open source it's very expensive – Shiva 13/10, 2013 at 19:46

Rails comes with performance testing built in: http://guides.rubyonrails.org/performance_testing.html

Anyone swear by this over other API's? – Adessive 11/1, 2014 at 10:23

This is not part of rails anymore, andwas moved to rails-perftest gem. – Edgar 14/2, 2020 at 9:31

If you want to visualize performance instead of just look at the numbers you might try Engulf. It's Open Source Software, distributed, and high-performance. http://engulf-project.org/#usage Disclaimer: It's a project I work on.
