if I need to see the amount of milliseconds / seconds a method takes can
I do something like this:

class Person
  attr_accessor :first
  def pl
    now = Time.now.usec #get milliseconds
    0.upto(10000) do |i|
      i = 'g'
    end
    now2 = Time.now.usec #get milliseconds
    puts String(now2 - now)
  end
end
p = Person.new
p.pl

whats the best way to do this?

class Person

  def pl
    now = Time.now.usec / 1000 #get milliseconds
    0.upto(10000) do |i|
      i = 'g'
    end
    now2 = Time.now.usec / 1000 #get milliseconds
    puts String(now2 - now)
  end
end

p = Person.new
p.pl

whoops, forgot the /1000
