Subject: Ruby vs Perl performance

I have downloaded perl and ruby program in net.I run both the
programs.But the Ruby program performance very wost than perl.Can any
one tell me the reasons and
soultion to make ruby as faster than perl.
I have attached perl program.


#!/usr/local/bin/ruby

BAILOUT = 16
MAX_ITERATIONS = 1000

class Mandelbrot

        def initialize
                puts "Rendering"
                for y in -39...39 do
                        puts
                        for x in -39...39 do
                                i = iterate(x/40.0,y/40.0)
                                if (i == 0)
                                        print "*"
                                else
                                        print " "
                                end
                        end
                end
        end

        def iterate(x,y)
                cr = y-0.5
                ci = x
                zi = 0.0  while(1)
                        i += 1
                        temp = zr * zi
                        zr2 = zr * zr
                        zi2 = zi * zi
                        zr = zr2 - zi2 + cr
                        zi = temp + temp + ci
                        return i if (zi2 + zr2 > BAILOUT)
                        return 0 if (i > MAX_ITERATIONS)
                end

        end

end

time = Time.now
Mandelbrot.new
puts
puts "Ruby Elapsed %f" % (Time.now - time)

                zr = 0.0
                i = 0
