Description:
Good evening!

When working with large text documents (200 or more pages), LibreOffice slows down. I was able to determine the cause - when the Navigator is open in the sidebar (for navigating through document chapters). How to fix it?

Version: 24.2.7.2 (X86_64) / LibreOffice Community
Build ID: 420(Build:2)
CPU threads: 4; OS: Linux 6.8; UI render: default; VCL: gtk3
Locale: ru-RU (ru_RU.UTF-8); UI: ru-RU
Ubuntu package version: 4:24.2.7-0ubuntu0.24.04.1
Calc: threaded

Steps to Reproduce:
1. Open big text file (more than 150 pages) and hube table of content (5-10 pages).
2. Open navigator (side bar).
3. There you have it, freeze and slow working.

Actual Results:
Slow working, freeze

Expected Results:
Fast and fine working


Reproducible: Always

Please attach a sample file, reduce the size as much as possible without private information, and paste the information in Menu/Help/About LibreOffice, there is a copy icon.

Being a very huge and complex file, it seems to work fine for me. Not too fast, but it doesn't freeze.

With MS Word it is really slow.

I want to confirm (as does my namesake) that there are problems in the version 24.2.7.2  But when I started trying: inserting my pictures. Adding pieces of text, etc. - I felt noticeable "freezes". The occupied memory increased by 6.5 GB. Although it didn't hang, but even that: thank God.
