As reported in https://gitlab.gnome.org/GNOME/evince/issues/745
-->snip<-- Opening PDFs scanned with my Brother Laser Printer is virtually impossible. The opening causes a 100% CPU spike on one core and does take forever.
The PDFs were generated in PDF/A by the Brother scanner unit. I have attached one for testing. I did not have this problem on Mac OSX, but Microsoft Edge seems slow on opening these files too. Chrome does process them with no mayor delay.
PDFs not from my scanner, like digital invoices I get regularly, do not produce any problem. -->snip<--
It is noticeable slower than Acroread, which is instant, and xpdf, which is almost instant.
