        <pre>Description:
We have tried to work with a formula with large data process.  

While process is going on for more than half an hour, we found that soffice.bin
only using 12 to 13% CPU.  Also while we checked CPU core's graph's it shows
only 3 cores used out of 8 cores.  We run the process on Intel i7-3770 cpu
@3.40 GHz, with 64 bit OS and 8 GB RAM.  Installed software is also 64 bit &
Libre Version 7.0.4.2.

Hope this information will help to improve the LibreOffice performance.

Steps to Reproduce:
1. Tried to rerun the software with same query
2. Added CPU priority with High
3. Manually selected CPU affinity, but same core counts used.

Actual Results:
Same as described.

Expected Results:
Need to use all CPU cores for faster performance.


Reproducible: Always


User Profile Reset: No
