In case you didn't know, a new virtual machine for Ruby called YARV (Yet Another Ruby VM) has been integrated into testing for Ruby 1.9.

In my own (very informal) testing, I've gotten speed ups of 2x to about 8x.
You can download it from the ruby-lang.org website.

Also, take a glance at this page for some benchmarks. http://www.antoniocangiano.com/artic...us-vs-cardinal

EDIT: I thought I'd add a little example.

def fib(n)
  if n < 3

  else
    fib(n - 1) + fib(n - 2)

fib(34)
def fib(n)
  if n < 3
    1
  else
    fib(n - 1) + fib(n - 2)
  end
end

fib(34)
