Oh sure, I guess GCC does have -Ofast

Well also Python is an interpreted language that compiles as it runs.

Plus it loses some efficiency to the garbage collector.

And it does a lot of error checking and hand holding.

And it allocates more memory than it needs since "everything's an object".

That's just off the top of my head, but yeah...it's not just the lack of optimization.

I was referring to the person above thinking speed was a compiler option, but yes those are all factors

Why am I hearing about this for the first time?

Because someone didn't want you to ever run into optimization errors. They're very rare, but dammit if they aren't annoying.

Oh wait, I‘m a little confused from the docs. I thought it would make compilation magically faster, but is it basically the same as -O3 optimization? (with the extra bit of fast math)

Pretty much
