title: Rails gems/tools for performance benchmarking?
body: <p>I'm looking for tools to monitor/test performance in rails, and I'm not having much luck finding anything particularly effective. I've read the rails 'performance' guide, but I use RSpec instead of Rake:Test, so I'm not particularly keen to use the rake:test framework.</p>
  
  <p>So, what do folks use for performance testing in rails apart from the rake:test benchmarker? Any suggestions appreciated</p>
