I have a heavy FormArray inside a FormGroup (plus than 200 FormControls), and i face performance issues with this ..

this.form = this.formBuilder.group({
      // ........
      ecritures: this.formBuilder.array([])
})

When we see the formControl object :

We can see that's it a heavy object, then that's caused slowness ..

I think to remove fromGroup and use only javascript to solve this problem, i will appreciate any other idea to solve this problem ..
