Why is backup using only 1 thread?
I have 8 logical CPUs in my computer. Older versions (like ATI 14) use to use all CPU cores.
Obviously since it's using 1/8 the threads it is 8x slower...

Hi Slava,
Thank you for your reply and description. However this is not how it's working in real life. It uses only 1 core throught the "Calculating time remaining" and after the label disappears.
Through all parts of the backup process only 1 core is in use.

Pro-logic. What is the affinity set for on your system with this application? By default, on my Windows 10 x64 Pro system shows affinity set to run on all 4 cores. Running a backu shows all 4 logical cores of my i5 chugging along as well.

The cpu affinity is set to all 8.
I have attached screenshots of the CPU use and Disk use.
For the record it's backing up from a RAID 0 to a WD Red. So throughput should be a lot more then 4MB/s.

4Mb/s is really slow. Is this locally attached or a NAS device? Even a USB 2.0 drive with a 5400RPM drive should be getting closer to 20Mb. I typcially only see low throughput like that when backing up to a network share where there is a bad connection (wireless?). I'm at a loss for why your system would only be using 1 core as I cannot reproduce the scenario on any of my home systems.
