Physics Frame Time in profiler too high

Godot Version

4.2.1

Question

How do I read this value on my profiler?

Hello, i have a little problem with some spawn I programmed for my game. In other scenes it works perfect, but here looks like something its wrong(even with an in progress level with a couple things compared with others i did).

I have mini freeze when I touch an area 2d that spawn an enemy. The problem is when I see the profiler, I dont know where to look for problems.

This is what i see:

As you see, for a fraction of time, its very overload. But what physics Frame Time exactly means? is there any place to look for some method or specific line that is struggling when the program try to execute?

update:
Ok, I really don’t know why, but if I put another spawner(another area2d)… works fine… not even a little spike on the performance graph
