Tools to test pdf compatibility and speed?

I variously use k2opt with -mode copy and -dev dx and Ghostscript with -dCompatibilityLevel=1.4 to pre-process pdfs for my Kindle Dx.

I sometimes use k2opt with -mode copy and sometimes -dev dx and then OCRmypdf with -f --output-type pdfa-1 to find readable text on pdfs without it or with corrupt text.

I occasionally use PDF to EPUB+, but it can screw up formatting, and it is a hassle if I need to cite page numbers.

I used to use Ghostscript with more aggressive options, but it would lose pages.

These tools *should* cover compatibility with the Kindle Dx, but Ghostscript sometimes yields very fast pdfs... and sometimes very slow ones that take several minutes to turn a page... forcing me to turn to k2 after all.

Is there any easy way to check for compatibility issues, missing or corrupt text, malformed pages, and/or speed?
