While I agree that Python isn’t a particularly fast language relative to Java, C, C++, etc (although, can we be fair, here? They’re both scripting languages, and on top of that, Python is backed by who, again?), I invite you to to improve the speed of either.
That said, I’ll admit to being a bit puzzled by some of the claims in this article; while yes, Python often benchmarks faster than Ruby, it’s not usually a night-and-day difference.. and Ruby absolutely pulls ahead in some measurements/benchmarks.
Anyway, overall, good article, thanks for sharing :)
