performance - timing code in ruby/rails -

-

i have rake task/batch job taking long , im trying track down in production time being spent. have started adding:

   start_time = time.now     # logic     end_time = time.now    elapsed_time = end_time - start_time    puts "elapsed time #{elapsed_time} logic"

is best way this? dont want install external tools in production. need finer grained timings method levels, because need know data being used each method/section etc.

i think you'll bang buck using profiler (like ruby-prof). show time being spent.
