<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
Additional Info:
No</pre>
