>"Mozilla's benchmark from December 2013 showed significant improvements: "Firefox with float32 optimizations can run all those benchmarks at around 1.5× slower than native, or better."[7] Mozilla points out that the performance of natively compiled code is not a single measure but rather a range, with different native compilers (in this case Clang and GCC) delivering code of differing performance. "In fact, on some benchmarks, like Box2D, FASTA and copy, asm.js is as close or closer to Clang than Clang is to GCC. In one case, asm.js even beats Clang by a slight amount on Box2D."[7]"

they could be written in C and compiled into javascript baaka

you could keep using the same software you use now if its opensource, infact it might even be faster thanks to software vs hardware based memory privacy

>70% cpu during idle

Can't wait

>written in C and compiled into javascript
How the fuck does that solve anything you retard? It would still be fucking slow because of javascript interpreter. And it doesn't even solve the portability problem.

I'd tell you to kill yourself, but then you'd stop posting Marie.

you're retarded, if you had read my posts you would have noticed that I addressed the speed issue. Yes C compiled into asm.js can actually be faster than 'normal' C.

I even posted a specific example where it was faster already, and that isn't even taking into account the many improvements that would be made once we start trying (that I also mentioned btw)

>>59715830
>Yes C compiled into asm.js can actually be faster than 'normal' C.
Except that's literally not possible.
An interpreter cannot be faster than bare hardware, especially when it's the same language and code being compiled onto the two execution platforms.

Whatever fake article you're citing is full of lies and retardation.

>>59715867
Explain to me how it's possible, assuming both compilers are equally optimizing, that C compiled to JS can be faster than the same C compiled to machine code.
It's retarded nonsense.

The interpreter would ALWAYS have more overhead than the compiled version.

btw in the end when javascript reaches the eventual parity with c compiler on majority of programs, it will immedietly be 20 - 30% faster anyway thanks to software based memory protection instead of hardware based interrupts and traps

even with a 10-20% vm overhead this is still faster in the end

I want to touch Marie's no no zone!!

>>59715973
No goalposts have moved.
Remember when I said
>assuming both compilers are equally optimizing
Take a look at the gcc bar, it thoroughly btfo's everything else. Clang is not mature yet and when it does get mature, it will be on the same level as gcc, btfo'ing firefox.
JS will never objectively be faster than compiled code. Sorry.

>>59715998
All it proves is that Clang doesn't optimize well enough.

>>59716009
the only mathematical advantage you have is vm overhead which I already btfo hhere: >>59716005

Do you have loli 3d models?

>>59716005
>btw in the end when javascript reaches the eventual parity with c compiler on majority of programs
Will never happen for as long as javascript is interpreted.

>thanks to software based memory protection instead of hardware based interrupts and traps
That will make it slower retard.
>Checking memory accesses EVERY TIME in software
Not to mention that your CPU will ALSO be doing the same thing, since you can't turn it off, so that's even more added overhead.

>>59716005
How are you going to do software based memory protection on hardware? Are you trying to browse the webs with software running on imaginary hardware?

>>59716044
>That will make it slower retard.

wrong, microsoft study says 20-30% speed improvements using software

>>59716045
the same way your browser 'protects' one tab from another, there will be no memory protection done on chip

>>59716054
So you are saying there will be software based memory protection but no memory protection? Good luck shitposting with your imagination

>>59716054
So basically you're forbidding any and all native code from running on the system besides the kernel?
That's fucking retarded.

Also, that would open up the system to a fuck ton of security problems since the interpreter would be running in fucking kernel mode.
Any exploit found in the interpreter and your system is fubar.

>>59715799
That's the most retarded thing I have read in years.

>>59716076

>>59716087
>how often javascript escapes sandbox today?
All the time.

The more major something is, the more attention it gets.
Many people are definitely going to dedicate their time to finding exploits in the interpreter, and they WILL find those exploits.
And once they do, they can wreak absolute chaos on everyones systems.

obviously more work will be given to fixing exploits once its used, example CURL in C is written in one of the most unsafe languages in the world but its constantly and forever probed for issues and avoids any major security holes

javascript is the biggest codebase and the most programmers in the world to be dedicated to this problem

not to mention javascript interpreter can be freaking tiny

>>59715830
>MUH SYNTHETIC BENCHMARKS!

Spend some time on code competition sites and pay attention to algorithm execution times (obviously with samples from people who took the same approach to the problem). In order from fast to slow:
C
C++
C#/VB.NET
JavaScript
Java (yes, Java is fucking slow)
Shit like Haskell and Scala

C and C++ are typically close. C#/VB.NET are typically decent but several times worse than C/C++. JavaScript is slower again by a few times. Java is absolute shit, and only meme languages like Haskell are worse.

Python is either shit or surprisingly decent. When it's decent, it's actually faster than JS.

So I don't want to hear about your synthetic (and likely 'fine tuned') benchmark bullshit. Java fags will claim they're just as fast as C to. In reality Java is one to two orders of magnitude slower than C. Sometimes even worse.

thanks for the marie pics
