CPU usage spikes to 110-130% (across 4 cores) when a large document (~260 pages, mainly text) is opened.
Steps to Reproduce:
1. Install LanguageTool extension
2. Open large file
3. Observe sustained spike in CPU usage and fan spin up
4. Close file
5. Observe CPU drop and fan spin down
When LanguageTool is installed, opening a large document will send LibreOffice's CPU usage skyrocketing. After a few minutes (depending on the size of the
document), the usage does eventually drop back down below 5% again.
When uninstalled, opening a large document inhibits a short spike in CPU
usage, but quickly drops off.
Small spike in CPU usage while opening, overall slight increase in CPU usage, total to remain >5%

So why open a new issue even though you saw bug 115757 already exists?
