Hi,
I do not like to check the source code to see what exactly happend.
Could you tell me, is there a performance different between string
"..." and '...' for simple string no parameter substitute.

For example, I saw a lot of code like :

puts "This is a String."  # case (1)
which is exactely the same as
puts 'This is a String.'   # case (2)

It seems to me most programmer always use "..."
no matter it has parameter subsitute or not.

I like to know for simple string, like example above,
the case #2 will "faster" then case #1 ?

( if yes, I will "set up" my habit, when a simple string
always use '...' )

Thanks for your help.
