How about something just like:

on my Mac, the 1.8.2 runs about 46% faster than 1.8.6

------


n = 1_000_000

start_time = Time.now

for i in 1..n
  t = (1..10).inject {|x, y| x + y }
end

finish_time = Time.now

p t

puts
print "Ruby ", RUBY_VERSION, " patch ", RUBY_PATCHLEVEL, " on ", 
RUBY_PLATFORM

puts
print "It took #{finish_time - start_time} seconds to run."
print " #{(n / (finish_time - start_time)).to_i} iterations per 
second.\n"
