Question

Hi,

is there a profiling gem/plugin for Ruby on Rails?

That is, where I can then specify the point in a request I want to act as milestones points for a time to be taken, and place them stategically. Then ideally the plugin then works out and displays how the overall response time was made up...

Tks

Answer 1

There's a new Ruby on Rails web-server in the block, which includes a pretty smart profiler inbuilt. You may like it...

Answer 2

Could you try ruby-prof? Basically start and stop the profiler around the parts you are interested in, and the profiler breaks it all down for you. Some example output can be found here.
