Scanning for files is slow

Hi, I am loving the nextcloud over wireguard experience so far!

Quick question. I am using sudo -u www-data ./occ --all files:scan to scan and add existing files to my NC DB. Nextcloud is running inside Ubuntu 20, 30GB RAM and a 16 Core CPU PC. The files are about 300GB. This command is very slow. I mean, its working but its really slow. It has been a day but the files are still added.

Is there a way I can utilize the full performance of my PC to do this?
