basic millisecond code profile?

[Aaron Smith]

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?
