Ruby faster than Python???

Steve Litt

Hi all,

I read somewhere that Ruby is quite a bit faster than Python. Is
that true? Is it true under most circumstances, or just in special
cases?

The same article also said Ruby was somewhat slower than Perl :-)

I'm sure you could find special cases to favor either, but in general
I would expect just the opposite. Python's got quite a few clever
optimizations (as I understand it), and Ruby is known to have a few
speed issues.

Definitely, yes. In my experience, Perl is quite a bit zippier for
many operations.

There's a reason we're all excited about YARV... ;)

Current version (0.3.3) of YARV shows already a big boost on execution
speed.

No. Generally speaking, Python is faster than Ruby.

True.

If you encounter performance issues, the profiler is your friend! :-)
The bottle-neck is often the programmer, not the interpreter :-P
Furthermore, Ruby will be significantly faster with YARV (Yet Another
Ruby VM) http://www.atdot...

Definetely, Eric. I used the future tense "will be" to indicate the time
when Ruby implementation will be based on YARV instead of the current
interpreter.

If it can run your code, that is...
