I do think performance was meant as "recognition accuracy". Altough i
rather advertise tesseract and free solutions, we can only recognize
that proprietary tools such as finereader have better recognition rates,
structure analysis, and format conversion (as for .odt)

it's precisely finereader v11.1.9.622165

there are three ways of using this OCR package:
  - it is integrated to the caja file manager in mate (maybe later in nautilus if interest is there), so one can right click -> launch OCR on files
  - one can bind a shortcut to your favorite window manager, and launch and scan + OCR and get the results in a libreoffice document.
  - users can have access to more flexible options by cmd line
these features are available without difference with tesseract, or
finereader. So one can use tesseract transparently, including with PDFs,
but one will get better recognition with the proprietary engine.
