Is this maybe a duplicate or co-issue to #13461?

If this file has a lot of changes in it and maybe even some pictures and graphics, then It seems to be an issue in Jaws too, but I must confess, I've nnever ever created or tried to edit a file quite that long! Some machines and processors also affect this, so I wonder if it is the multiple calls it has to make which is the issue. Can you perhaps cut the file into smaller ones?

Hello,
That file I was editing, is a text-only file, without any images.

the biggest impact on performance in this case is the setting "reporting of pages" in NVDA settings, as we found out in #2296. I am closing this issue in favor of that one. Apart from that the performance has got far better meanwhile, but it still needs to be improved.
