Thank you.  It helped me set up this example:

   require "benchmark"
   include Benchmark

   data = (0..49999)

   bm do |z|
     z.report { n = data.inject(0) { |x,y| x += y } }
     z.report { sum = 0; data.each { |y| sum += y } }
   end

Results here:

       user     system      total        real
   0.280000   0.000000   0.280000 (  0.280593)
   0.100000   0.000000   0.100000 (  0.101712)
