WinClone 8 very slow

I’m using a 16" MacBook (16GB) with Catalina. I have 2 x 120 GB SSD Disks, same model, connected via USB-C. Both SSDs are 100% identical. I’ve made them bootable with EFI and everything works fine. But if I want to clone the Bootcamp Partition it takes hours, even if I “block based imaging”.
Creating an image is fast, but restoring it takes a lot of time -When I’m writing this post, the restore is running for over an hour now - for 40 GB.
What can I do?

Thanks for help


It sounds like antivirus, security or backup software might be slowing things down (pretty common with MS Security Endpoint). Try disabling.
