Is there a way to force Calibre to use all 4 cores of my CPU when doing tasks?

Can I get Calibre's conversion tool to use more just one CPU of my quad-core computer? In 5 minutes, it's still at 1%. My computer shows CPUs 1, 3 and 4, not being used much. So why not let Calibre use more of my laptop's brainpower to speed up the PDF-to-Epub conversion?

Convert more than one book at a time and it will use multiple CPUs
