A desire for one performance for that LibreOffice Writer
Steps to Reproduce:
Dear LibreOffice Team
I would like to suggest a suggestion for the LibreOffice Writer, which I would be very happy if you could fulfill them in the upcoming release.
My suggestion is about the performance of LibreOffice Writer. I write documents that have over 600 thousand words and are over 700 pages long, which causes the writer to lose performance and no longer run smoothly, even sometimes threatening to crash if I try to find spelling mistakes with the spell checker, which takes ten to fifteen minutes Because of the size of the document, even though I have a power PC and the CPU gets bored, LibreOffice is not usable at all during the spellchecker, which prevents me from reading or editing another document.
The performance has to be improved somehow, so this does not happen. It is very annoying when LibreOffice crashes during the process, because the spell checker does not follow and you have to start over again because it could not be saved.
Thank you for your attention and look forward to the upcoming releases of LibreOffice.
Yours sincerely, J. Schulte

Out of curiosity:
* a native ODT document?
* a complex document (images/frames/tables) or text only?
I dont use iframse/images/tablets.
I use only letters on my dokument because its a Roman.
1. There all sorts of slow down issue with larger files. Lots of comments & tracking changes are the most common. For example bug 92011
2. Are you able to recreate a file using with the same behaviour? Using - for example - text from wikipedia in the language in question.. A sample file would help!
Thank you for reporting the bug. Please attach a sample document, as this makes it easier for us to verify the bug.

See https://wiki.documentfoundation.org/QA/FAQ#How_can_I_eliminate_confidential_data_from_a_sample_document.3F for help on how to do so.)
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' once the requested document is provided.
I will create a Dokument with the same problem and it will provides.
I create a new Dokument for you and I come on 1,8 GB RAM and the performance ease up but it is not so bad as by my roman. Around that adjust the scenario, is it important that the extension "LanguageTool" installed and activ is, around on 1,8 GB. The performance does not differ if this "LanguageTool" on or off is. Only RAM is affected to get.

1. Open https://drive.google.com/file/d/1NPXKo2nsfn9steLOw1AuWvZxQE21wT-n
2. Wait until CPU usage drops to 0%
3. Use the right click menu to correct a spelling mistake
with or no "languageTool"?
i have never CPU usage drops to 0%(In reply to J. Schulte from comment #8)

With "Automatic spell checking" enabled, default extensions, dictionary.. The CPU usage of soffice.bin should drop to 0% in around a minute or so after file-opening (depending on system specs).
Can i create Video for you?
(In reply to J. Schulte from comment #13)
Hmmm, interesting. This is indeed something else.. Does this also happen in safe-mode: Help -> Restart in safe mode
Video is comming
You might be interested in comment 13. It's leaking pretty bad, for some reason..
I upload a video with my Roman.
I hope you Understand my problem better now.
Setting back to unconfirmed for now. I'm not able to reproduce the problem as illustrated in the youtube video's.
When it shouldn´t help i will search for a better methode
You can't confirm your own bugs. Moving it back to UNCONFIRMED until someone
else confirms it.
This is not a proper https://wiki.documentfoundation.org/QA/BugReport.
Non useful title and not specific repro steps.
I can see in 6.2+ attached 750-pages ODT is somewhat slow and keep CPU at 13%. Guess because it's recounting words and characters. Using spell checker is also somewhat slow but it works. Can't say now if it's due to my i7 or 6.2+. I didn't test with LanguageTool.
I set back to Unconfirmed.
- write reproducible steps and propose specific title
- test both with and without LanguageTool
- please test with previous (like 4.3.7, 4.4.7, 5.0.6, 5.1.6, 5.2.7) and future versions (current master 6.2+), using Separate Install GUI tool http://tdf.io/siguiexe. It downloads and extracts different LO versions, without installing, so you may test different versions

I let it run for over an hour after the GUI appeared, hopefully captured enough data.

Is it a regression? At the side of LanguageTool and/or LibreOffice.. Not volunteering to bibisect :-)

This is my last video, because i dont speak english and use google translate and i have no fun more.
Ich kann kaum englisch, weswegen ich mit den Fehler leben werde oder nach einer Alternative suchen werde, denn ich kann mit diesen Laggs und Hänger nicht leben und auch nicht tolerieren. LibreOffice 6 ist kein Fortschritt, gegenüber 5, weswegen ich ein Downgrade durcghführen werde. Ich gebe es auf.
Mein Problem ist, dass LibreOffice kein Multitaking unterstützt oder nur ungenügend. Sobald es hängt, hägen alle geöffneten Dokumenten und wenns abstürzt, stürzen alle Dokumente auf, was wirklich ungenügend ist.
Ihr könnt euch diesen Problem widmen, wobei ich sehr stark bezweifele, dass hier überhaupt was passieren wird, weswegen ich jetzt die Hoffnung aufgebe und euch viel Spaß wünsche.
Vielleicht kriegt ihr das Problem, durch die Hilfe von anderen Programmierer, hin, aber ich kann euch nicht helfen.

I don't think so. I tested on Win and even 4.3.0 keeps the CPU going. Strangely, I tried with bibisect repos, but in their builds the CPU calmed down after like max. 1 minute. I took care to install https://extensions.libreoffice.org/extensions/languagetool and that the German dict was installed and automatic spellchecking enabled.
Note: in 4.3.0 one enables the auto spellcheck from toolbar.
Here is the German dictionary for the convenience of future testers: https://extensions.libreoffice.org/extensions/german-de-de-frami-dictionaries
I also tested LT 3.9 on Linux master and no change in behaviour.
