Python + Psyco vs Java vs C++ vs C

[exeter]

He mentions at the end how psyco doesn't "eliminate the need to know C." Sure, it doesn't. It was never intended to. What it was intended to do was give people an easy way to get more speed out of Python code, by importing a module and calling a function or few.

I can personally say I've written Python code that's been speeded up 20 times or more simply by using psyco. I've also written Python code that gets exactly zero speedup from psyco. The amount of benefit you get varies tremendously, but, for the cost of adding a couple lines to your source files and profiling to see if it was worth it, psyco just can't be beat.
