How to profile Ruby 1.9 and/or JRuby code? (ruby-prof works only on MRI Ruby 1.8)

I love ruby-prof, but it unfortunately does not work neither under
MRI Ruby 1.9 nor under JRuby. How can one profile MRI Ruby 1.9
and/or JRuby code?

(I can try backporting my code to Ruby 1.8.7, but it’s additional work
and I doubt profiling for Ruby 1.8.7 will consistently make the code run
better under Ruby 1.9 and JRuby.)

It appears from the ruby prof log that they *used* to support 1.9 (till
1.9 changed), so I'd probably fork their code and try to fix the compile
errors in it.

you can use ruby - prof on 1.9 but looks like you'll have to check it
out from SVN trunk to get it to compile :slight_smile:

svn checkout svn://rubyforge.org/var/svn/ruby-prof
