Subject: Ruby "Speedup" hints?

Anyone of you has a few hints on how to speed up ruby code?
(Note - not writing it, but running it ;-) )

I only have a few hints, like 5... would love to extend it.

So without further ado:

- Using << instead of += for Strings as += creates a new object
whereas << will simply work on the current object.

- Use Inline C for critical methods (had to include that ;> )

- Reusing variable names might be better than using a lot of
different variables

-  for is faster than .each on Arrays

- .last is faster than [0]

- .zero? is faster than == 0


If you know a few more hints, please add!
