DeDup Runs Super Slow - any ideas

Your software
My Mautic version is: 4.4.1
My PHP version is: 7.4

Following my post on duplicate contacts being created I am now trying to run the Mautic:contacts:deduplicate and it is going soooo slowly, like checking 1 record every 2 or 3 seconds.

and I have a power server running the following:
8 Dedicated CPU

My DB size is just over 100K. Any ideas on why this is going so slow, it will take a week to deduce this at the moment :smiley:
