If you use an actual pdf reader instead of the JS-based in-browser crap, it's quite instantaneous.

Yeah, that's what I've been having to do on a lot of things lately. I told them what would happen when they first started pushing it. Looked at the person next to me to say, with all the things Win98 on a PII did, the modern era chokes a Core Duo 2 trying to look at a document in a browser. Unreal...

Interesting - in my experience pdf.js is faster than adobe reader... Didn't measure it though.

But javascript is so cool!

JS is also sandboxed, which seems to be a particular problem for traditional readers. I’d trust PDF.JS to get faster more than I trust PDFium to not have security issues.
