Object allocation is slower since 4.0.beta9

Godot version

v4.0 beta9

System information

Windows 11, 64bit

Issue description

Since migrating from Beta 8 to Beta 10, I've noticed a serious performance hit. I've tracked the problem down to a place where I'm creating a couple thousand objects. The object allocation used to take a couple microseconds, but ever since Beta 9 it takes hundreds of microseconds to construct a new object.

Steps to reproduce

Create a plain Godot class that extends Object. Create a few thousand of them. It takes a while.

If you can compile the engine from source, you could look into bisecting the regression to greatly speed up troubleshooting.

OK, I'll see what I can find.

I didn't test much, but I remember having this problem and that it might be fixed on newest master.

[maldrasen]

That would be awesome if so. I haven't been able to build from source yet, so I've yet to test it on master.

[KoBeWi]

Beta 11 might be released soon, so you will be able to test easily.

Can you still reproduce this issue using Beta 14?
