that slowness has nothing to do with download

i open it as local file

i believe pdf format used by archive.org is cause of slowness

they are scanned books, and allow you to select text, it's advanced (and complicated)

my viewer performs better when viewing  pdf files from other source

and my cpu is slower than that used by mainstream users
