Pages with multiple instances on CKEditor 5 are unnecessary slow

Problem/Motivation

We have nodes with paragraphs which contain ckeditor 5 instances.
Now i know i could load the paragraphs in a closed state but this is not what we're doing.

We're currently optimizing the author performance and benchmark the application with Blackfire and saw that a lot of code is executed for each instance of Ckeditor which i think we should be able to cache for each text editor format?

See the attachments of the timeline and the zoom into the getAttachments functions which i think we should be able to statically cache for each text editor format?
