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  
attr\_accessor :first  
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
