Stop writing crap code and then complaining that the language is "too

I write compilers for static languages, which are generally considered toys, partly because the code generated is not great.

But in a real application, the difference between my compiler, and gcc-O3 or MSVC/O2 might only be 10-50%. 1.1 to 1.5 times as fast (or as slow), and that's an application that does few external library calls.

The difference between Python and another dynamic language might be a magnitude, yet you say it doesn't matter.

Thanks, that makes me feel much better about my own work! If a magnitude difference in performance can be so casually dismissed.

"Python takes hours to sort a million integers using BubbleSort! Its too
damn slow!!!"

"Why not use the built-in sort? That's fast."



Have you ever written a benchmark in your life? If so, did it do anything useful? Other than what benchmarks are normally used for.
