Mozilla Pushes "Shumway" Flash Into Firefox

[LightBit]

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

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

Have you tried copying and pasting text from it?

Not until now. Haven't had a reason to

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

^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...

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..

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.

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

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

Maybe, but Firefox doesn't do that.

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++
