原文:
Every year, someone posts a benchmark showing Python is 100x slower than C. The same argument plays out: one side says “benchmarks don’t matter, real apps are I/O bound,” the other says “just use a real language.” Both are wrong. I took two of the most-cited Benchmarks Game problems — n-body and spectral-norm — reproduced them on my machine, and ran every optimization tool I could find. Then I added a third benchmark — a JSON event pipeline — to test something closer to real-world code. S…
