Benchmarks for stripe_event

Benchmarks

This document is a basic comparison of the performance of the stripe_event gem given different Rails Controller setups. StripeEvent::WebhookController only needs the head method provided by the ActionController::Head module. This means the controller can inherit from ActionController::Metal rather than ActionController::Base if ActionController::Head is included. I'd like to have some data to support this decision.

Performance will be measured with the Apache HTTP server benchmarking tool using the unix utility ab. The ab that ships with OS X Lion seems to be broken, so I installed the version with Homebrew: brew install ab.

The benchmarks will be run on a MacBook Air with the following specs:

  • OS X Lion 10.7.5 (11G63b)
  • 1.7 GHz Intel Core i5
