I have installed ruby-prof and test-unit as i am planning to use a ruby profiler to profile my website during development…
The problem is that when i type rails profiler into the console i get nothing…
shouldn’t i get some times my app took to load etc.. like codeigniter?
or maybe is there any similar profiler to codeigniter for rails?
Actually, yes, there is real alternatives RailsMetric, or Metrical, which one I prefer. You might want to know more about this last one reading/watching corresponding RailsCasts by Ryan Bates.
Yesterday, Sam Saffron announced the first released of MiniProfiler for Ruby according to this question on SO. I think this might respond better to your needs. For more informations, read the article on his blog.
