Source code in Mono (as in the Microsoft .Net tool) is first
->Compiled into a byte code (CLI, Common Language Infrastructure),
   --> And CLI code is compiled by JIT (Just in Time Compiler) into 
machine code.

So the first run is rather slow, but subsequent calls should hasten.

CLI spesification:
http://www.ecma-international.org/publications/standards/Ecma-335.htm

So it's not fair to compare Ruby's runtime against Mono or .Net.

---------------------------
RUBY needs a Parrot !

Parrot will be a "common language runtime" for dynamic languages such as 
Ruby, Python and Perl. It will be a competitor to (ecma's)CLI.

Parrot  will probably implement a JIT too.

Parrot project
http://www.parrotcode.org/docs/intro.html

http://www.linux-mag.com/2003-04/parrot_01.html
Page-5 has some explanation why implementing a new 'Parrot' and not 
targeting the existing (ecma)CLI and Java VM.

+ Dynamic type systems in Python/Ruby/Perl are too complex for (ecma's) 
frigid CLI spec!
----------------------------

But I would like to see some official comparison between PYTHON and 
RUBY. Have u seen any?
