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?

Thanks for the report. This was fixed by #81037, so closing as completed. I tested the MRP and it's much faster now.
