There are limits to everything, but Python works fine for this application.

Mass converting PDF files is a foolish waste of time. To have a chance at decent PDF conversions you need to review the converted file and adjust conversions settings as needed and do as JSWolf stated an A/B compare between the original and the conversion to make sure it survived as a readable document.
Bottom line PDF conversions are hit and miss because for so many years PDF was strictly a page layout format limited/confined by the size of the page. It was never previously meant to be able to be reflowable to fit different page sizes.

If you allow calibre full use of your machine it will use it. If you had decided to limit cores (Preferences - Miscellaneous) or job priority (Preferences - Behavior - Job priority -> Low) you could have been using your machine with ease this entire time.

When you twice resurrect 2 year old threads for the purpose of whining before you even investigate the features built into the program, by definition you are trolling.

Nothings perfect, but given calibre's success I would say that Python is well suited for this sort of application. The plugin architecture has allowed other developers to expand calibre's capability beyond its core function and the template programming language allows users to do all sort of customization of their library.

Trolling much? The
original directory structure has
NOT been altered in the slightest. When books are added to calibre the books are
copied to calibre's database so your original files and folders are not touched.

No program
converts PDF well. But you can use Adobe Acrobat to save books as html (even this is far from perfect) then use other programs to convert the html to ePub. Calibre is great at quickly converting html to ePub.
Good Reading.
