Type of report

Bug

Provide detailed reproduction steps (if any)

Open attached document and paste its contents into CKEditor.
Scroll to the bottom
Press and hold Delete key to delete characters or press and hold e.g. 'a' key to type characters.

Test File:Long Document.zip

Expected result

CKEditor works smoothly.

Actual result

There is a noticeable lag between key press and actual characters deletion insertion. obraz

Other details

NOTE: The more complicated the document and the richer the preset, the lag seems to be larger.
