problem with large project very long response times on mod==DEV on Windows

Play Version 1.8.0 --> JDK 17

problem with large project very long response times on production version on windows

the response time of one request slows down from 5ms to 150ms on linux and on windows from 8ms to 5.5sec

To Reproduce
Steps to reproduce the behavior:

get this project https://github.com/jacol84/bigPlay.git and skip to 5 step

1. create new project in plya
   play new
2. change Appliaction.java index method

    public static void index() {
        renderText("aaaa");
    }

4. create 50k file.java in ./project/app/com/mik
   my example

package com.mik;
    
public class Class1 {
    public static void main(String[] args) {
        System.out.println("Hello from Class1");
    }
}

5. run on windows / or linux
   play run
6. send a request and measure the response time

this project is my github https://github.com/jacol84/bigPlay.git

this result respon :
this result on DEV working
on windows (~5,5sek)

on linux(~150ms)

a project without additional files(~5ms)

Expected behavior
I would expect a response of around 10ms

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Windows 10 and 11
• JDK 17
• i use WSL to linux test

Additional context
the problematic method is play.Play#detectChanges when measuring

Reproduce the slowdown with the linked bigPlay project on Windows 10/11 using JDK 17, with 50k Java files and play run. Start by investigating play.Play#detectChanges and compare request timings with Linux and a small project. Done means identifying the Windows-specific cause and bringing the large-project response time close to the expected 10ms.
