Description ask4support 2017-10-01 14:30:55 UTC
Will LibreOffice ever support multithreading for searching (at least in Writer) and perhaps for filling huge ranges of cells? 

Steps to Reproduce:
Searching in Writer
0. Open the attached file
1. Press Ctrl + H
2. Click "Attributes..." 
3. Check "Underline"
4. Click "Other Options"
5. Check "Regular expressions"
6. Type ".*" into the search field
7. Press Find All

Pasting in Calc
1. Select entire column. 
2. Paste something. 

Actual Results:  
Single CPU core fully loaded and LibreOffice hung for some time. Once it was searching for many minutes before i killed it, I was unable to reproduce that long time again. 

Expected Results:
Multiple CPU cores used. 

Reproducible: Always

User Profile Reset: Yes

Additional Info:
I accidentally selected a whole column in Calc and pasted a number to all the cells in the column. I noticed that it also uses only one core. 

I ran LibreOffice with the different home directory set, so that I could switch to English, I believe it's the same as running from a clear installation.

As a performance problem, this rather looks like a duplicate of bug 100479.
