Both. Perl is around 20x slower than C for common tasks, while Python is around 133x slower than C for common tasks like looping, depending on what you're doing of course.

Perl is the ultimate mockup language in that you can crank out code very fast and get good bug free results. It lets you write in the way you think where other programming languages force you to write a specific way. Ofc you can get good at Python, so good at it you might get as fast as Perl. And Python is easier to read. The advantage of Perl, writing like you think, makes it difficult for anyone but you (or someone else who thinks like you) to read and maintain your code. The ugly code stereotype comes into play from this.

Perl isn't like Python. It's great if you want to write a one off script for doing quick analytics or a one off script that checks something on a server. It's fantastic for that. Python, you'd need to google around for a library, hope you find one, grab it, write a 100 lined file, and then finally be done, where Perl was a quick one-liner to do the same thing. Ofc the Perl is going to look like garbage and not be maintainable and the Python is going to look golden and be maintainable. They both fit a different need and different use case.
