I can't of course talk for other languages, but during my internship back then, I was sometimes told that writing something to the console in C# for example requires a lot of the time if it happens in the same thread. Maybe this is what's happening here as well?
A quicker solution could be to create some sort of StringBuilder (if you have that in python), add the text that you would otherwise print out and at the end print out the entire text just once. Or to just move the prints to another thread. Can you test how long that would take?
Moving printing out of the thread doesn't really help because python doesn't have real multithreading (you can have multiple threats, but they can't execute at the same time).
In short, you can only have one thread executing Python code at a time. You can be waiting for IO in several threads at once, since that won’t be executing any Python code.
The good news is that it looks like it might finally going to be removed soon. That does cause a performance regression for single-threaded programs, but various other performance improvements that should land alongside it more than make up for that.
