I was thinking that too, but perhaps he means 'execution' in the more generic sense of creating a product quickly?
In any case, even with a slow scripting language like Ruby, if the speed of the language is a concern, perhaps that part of the application should just be farmed out to a library in C (or a separate process in whatever language). Need more info, though.
I'm the Ops Co-founder. True C like languages are faster, but we don't need quite that much speed. nothing Scientific, or really mission critical. I mostly want the code to run faster vs ease of coding. So if the app was going to take longer running in php than python, but faster to code, I would still want python.
