I recently replaced a relatively simple text parsing/collating python script with a nearly-identical one written in perl, and the runtime dropped from ~30s to ~3s.

(The original script was python 2, and I started out by trying to port it to python 3. Unfortunately it needed to handle sometimes-broken unicode so rewriting it in perl turned out to be far more expedient. And as it turned out, an order of magnitude faster)

Anectdotally, the only times I've seen where python is "fast" is when you're able to hand off batches of data to native-compiled libraries. (NumPy being a prime example of this..)
