Tika uses the open source Tesseract OCR engine. Tesseract is optimised for
ease of contributions and ease of implementing new approaches, rather than
for performance, because as an (ex?-) accademic project that's more what
they think's important
There's some advice on the Tesseract github issues + wiki on ways to speed
it up, eg https://github.com/tesseract-ocr/tesseract/issues/263 and
https://github.com/tesseract-ocr/tesseract/issues/1171 and
https://github.com/tesseract-ocr/tesseract/wiki/4.0-Accuracy-and-Performance
Otherwise you'd need to switch to a proprietary OCR tool. I understand
that the Google Cloud OCR is pretty good, if you don't mind pushing all
your files up to Gooogle and paying per file
