Similar issues:
ckeditor/ckeditor5-vue#42
And:
ckeditor/ckeditor4#449

But then for CKEditor 5 and angular. I am experiencing the same issues and wonder how to fix this? I guess this has been brought up before but I can't seem to find any related topics on this.

This can easily be re-produced by opening the default template for angular ckeditor:
https://stackblitz.com/edit/angular-ckeditor
And paste large amount of text in it. Go to https://www.lipsum.com/, put paragraphs on 150 and just start copy-pasting that text into the edtior. Around 5 or 6 times it becomes slower. The more lines you have, the more slower it becomes.

I have tried to remove the [data] property so that there is no two-way binding, but I guess, just like in the vue project, there is an issue with the on-change detection.
