I've always been a fan of nginx & unicorn over Phusion Passenger, but when we launched (Stride)[http://strideapp.com], I wanted to challenge my assumptions on that, and we went with Passenger to launch. It was not fast, and quite a memory hog, and pretty quickly I flipped back over to nginx & unicorn, and we had a ton more traffic pushed through.

I wanted to actually benchmark different Rack-based http servers, so I made a simple Sinatra app, and hammered it on httperf. I plan to re-run these tests a couple times a year as servers are updated. If you find a problem or a mistake, I'd love to hear about it!

== The Servers

  • Phusion Passenger + Apache
  • Phusion Passenger + nginx
  • unicorn + nginx
  • rainbows! + nginx

== The App

The Sinatra app has two urls:

  • one that sleeps for 100msecs to pretend we're waiting on a database or external API.
  • one that returns a 500kB string, to pretend we're sending out a big chunk of data.

There's also static assets that need to happen in a little bit.

I plan to simulate more usage patterns at a later date.

== TODO

  • Better statistics - I'd love to have somebody who's better versed in stats give this a once-over
  • Automate the magic?
