    So in the end you came to say that it doesn't work for your pc yet.
    If you read the rest of the quote, you would see that I was referring to pdf.js, in response to a comment about pdf.js.

    But my expectation is that Shumway would be miserably slow here.

No kidding guys, so why have you changed my settings to use this one? I expect Shumway to be similar. At least there is a decent reason to create it, given the problems with Flash and Adobe's dropping support.

      By the way, is the Firefox PDF reader good yet? Is there any reason at all to use it?
      It works fine for my needs, but I don't deal with PDF's much. I'd wager it does the job just fine for many users that only need a basic reader. Only problem I've seen is it can be sluggish with large pdf's.

        Shumway is written in JavaScript, so I doubt. It's probably much slower.

            Can't you shove javascript through LLVM IR to get basically C++ performance out of it? I know you can do the reverse (C++ ---> LLVM ---> JS) but I could've sworn I saw a project to take the JS and make it into C++

              Maybe, but Firefox doesn't do that.

                They developed and use http://asmjs.org/ in all such applications. It is significantly faster than regular JS

                  I found their .pdf reader to be very usable. Doubt there's more than 1% of cases it completely messes up. Can't see shumway being defaulted anytime soon though..

                    Thats what I was thinking of, thanks Rahul. I knew they had something that was closer-to-metal than normal JS

                      Have you tried copying and pasting text from it?

                        Nah, it messes up far more often that that.
                        But it's still usable. Even if it messes up on some parts
                        most of the documents is still readable. And if I want to
                        see a "perfect" version I just click on the button that say
                        it did mess up.

                          Except, ya know, JavaScript performs MUCH faster in a browser than flash...

                          http://bubblemark.com/dhtml.htm
                          vs
                          http://bubblemark.com/flex.htm

                          ^Try 128 bubbles on each. On my computer at least, the performance is 40fps (JavaScript) and 13fps (Flash).
                          Flash Cached gets ~32fps, so that's pretty close.

                          As a side-note: The Java Applet (via Swing) version got 32-33fps. I always assumed Flash on the web performed better than Java on the web... guess I was proven wrong.

                          So if Shumway gets developed correctly, it could outperform flash at rendering it's own files without requiring a plugin (thus, without having to spawn a new process to run it, saving memory and crap). Just a thought...

                              That is because flash also has scripting. Shumway will have to "translate" that scripts which will probably be slower.

                                Does Firefox use this?
