Poppler allows saving annotations to the PDF? I thought it stored them in a local file, too.
thanks

Any one of these PDFs loads very slowly with Poppler.

Indeed, with Okular 0.19.1 some PDFs are still very slow.

By comparison, Chrome and Firefox mostly views PDFs faster than Okular.

Please note that it is the version of Poppler which is most relevant in these circumstances - as it is Poppler which actually renders the PDF files.

It seems PDF/A files are what render very slowly in Okular. I know they're PDF/A because when I open them with Acrobat Reader, it gives me a message saying I am reading them in PDF/A mode. Acrobat Reader renders the images in the PDF pages progressively and also much faster than Okular.

I don't think just blaming Poppler is valid here. Both Okular and Evince use Poppler as a backend renderer, but Evince is lightning fast, whereas Okular is unusably slow.
