While testing Regshot I recognized that write performance onto a shared folder is 3-5x slower than on the host. Writing onto a virtual disk is as fast as on the host.
To reproduce run Regshot 1.9.0, click "1st Shot", select "Shot and Save..." and save to the virtual disk.
Then click "2nd Shot", select "Shot and Save..." and save to a shared folder.
You will recognize the difference.
