OTOH, I have not had occasion to restore since I had a motherboard fire, destroying one of the usb ports, and put a new Asus X370 mobo, a 6 core 3.7GHz I5, and 32 GB of dram behind that same set of drives and rebooted. My thoughts are that with that much memory to play with, it probably will not have a problem. My backups are running, doing 5 machines with the compressible stuff being fed to gzip -best, in usually under an hour for nominally 20 to 30GB written to a 2TB drive.Are you able to monitor memory useage while amrecover is running, with something like htop? Might be educational for both of us.
