Run Calibre 4.23 from a CLI and use the option --ignore-plugins. Then check to see how much processor it is using. It could be a plugin causing the 10%. It's not Calibre itself. Or it could be your AV. Turn off your AV and try with the plugins to see if that fixes things.

Code:
Calibre --ignore-plugins
