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

bug 65046 is pretty old.. there is multi thread for calc.. so prefer small investigation first Is it possible to recreate a dummy testing dataset with the same formula. It sounds to me like the formula is causing a fall back to single thread

It > sounds to me like the formula is causing a fall back to single thread Thanks Telesto, Here is the formula we used to test performance: =INDEX('file:///D:/Main Data Do not Delete/Desktop/ZCA51.xlsx'#$Alt.$A$1:$C$1048576,MATCH(A5,'file:///D:/Main Data Do not Delete/Desktop/ZCA51.xlsx'#$Alt.$B$1:$B$1048576,),3) If need I could share my screen by remote, so it will help to resolve it better.
