Some guy blogged about JRuby and CPython performance. For the most part he’s gloating that his stunning prediction that jruby would be slower than cpython has come to pass.

Get this man a Nobel…

Is there a single person in the Ruby, Python or Java communities that is surprised by this? At a minimum I’d argue that comparing Jython would be more appropriate but quite honestly, who cares? No one is using Ruby, or Python for that matter, for their blazing speed. It’s well known that both languages have speed issues and Ruby is definitely the slower of the two.

Hand tuned assembler may be faster than Jython

If you want speed, don’t use Ruby or Python. People aren’t turning to these languages for their performance characteristics. They’re using them for the sheer joy of working in these environments. I like both Python and Ruby, they have their strengths and weaknesses. In Ruby I find myself wishing for Twisted all the time. In Python it’s Ruby on Rails, I’m sorry Django, you’re beautiful but it’s really a personal style call at this point.

I can has pots and kettles?

Seriously, this is like a bunch of tortoises arguing who’s fastest. You’re all fucking slow compared to your competitors. Get over it and pick your fights more carefully. Focus on your strengths. The Ruby and Python communities have a lot in common and should focus on common ground instead of arguing who sucks at performance least.
