Firefox JaegarMonkey Test Drive

[Smoore]

JaegerMonkey is the new JavaScript engine coming in Firefox 4, and it looks to be as big a jump in performance. You can try out JaegerMonkey in special preview Firefox builds.

Everything else in these special JS Preview builds remains the same as with the Firefox 4 betas, but the JavaScript guts have been upgraded. Running these builds through the same kind of benchmark suites we use in our performance tests, the ReadWriteWeb blog found that JaegerMonkey outperforms the current Firefox 4 betas handily, but is still a solid distance behind Chrome. In real-world usage, though, the test builds felt pretty snappy on script-heavy sites like Gmail and a Google Wave test.

Try out JaegerMonkey for yourself and see if the speed is there. The preview builds are free downloads for Windows, Mac, and Linux system

Wow. :w00t:

Firefox will come near Chrome for sure. ^_^

[oZ.]

um ill wait for beta 6

Tools? None. Website? Here you go. Please note. The numbers depend on the power of your CPU. And I try to keep my CPU almost at same speed for all the browsers when I benchmark. ;)

The latest pre-Beta 6 Builds of Firefox 4.0 bring to the table a dramatic increase in performance associated with JavaScript.

This because the new nightly builds offered by Mozilla earlier this week contain the next generation JavaScript engine for the open source browser, codenamed JägerMonkey.

Early adopters can now download Firefox 4.0 pre-Beta preview nightly Builds and start test diving JägerMonkey.

Still, users need to keep in mind that the releases are very early versions of Firefox 4.0 Beta 6, designed for testing and not for deployment into production environments.

Fact is that, Mozilla still has to merge all the JägerMonkey code into Firefox 4.0 in order to produce the fully fledged beta 6 of the browser.

“JägerMonkey is our new optimizing JIT compiler for JavaScript. It sits underneath our existing JIT, TraceMonkey, which appeared in Firefox 3.5,” revealed Mozilla’s David Anderson.

“JägerMonkey is a general-purpose compiler which converts entire methods to machine code. The goal is to get great baseline performance.

“When it detects a loop that can be traced, it automatically engages the trace compiler, which makes it even faster.”

Anderson explained that this is roughly the equivalent of having a turbo button inside the browser.

“This hybrid approach is designed to use well-established optimization techniques that work everywhere, and combine them with our existing hyper-optimizing engine that handles smaller subsets of code,” he explained.

The promise from the browser vendor is that testers will be impressed with the new JS performance delivered by Firefox 4.0.

Mozilla has already run some tests, and the results speak for themselves. Firefox 4.0 Beta with JägerMonkey wrapped up SunSpider 0.9.1 in just 304 milliseconds, twice as fast as Firefox 3.6 (621 ms) and certainoy faster than Firefox 3.5 (726 ms).

According to the results of the V8-v5 benchmark, Firefox 4.0 with JägerMonkey is four times faster than its predecessor with a score of 3,254 compare to just 738 for Firefox 3.6 and 561 for Firefox 3.5.

Anderson noted that “at the same time, here are some of the immediate performance works-in-progress:

1.Function Calls. This is one of our last big areas of optimization. The first of four major pieces, caching call sequences, was completed this week.

2.Tracer Integration. Right now we’re just scratching the surface, and we will have much better heuristics by the end of the month.

3.Web Optimizations.”

good news

[DreamHaters]

Great news to hear :dance2:

[donizme]

Didn't see that coming! My thoughts of switching to Chrome are now on hold. ^_^

[DKT27]

Topics Merged. ;)

I just can't wait. :w00t:

But will only test the betas. :(

[bashar]

let's see , if they're going to top the rank with this 

I'm waiting ....  :sneaky:

[DreamHaters]

I think im going to fully test Beta 6, Specially because of the new Java Script.

2nd Half of September (tentative)

Can't wait :D

[Bizarre™]

Indeed, wait for Beta 6. As of right now, nightlies consume too much CPU.

[Sl@pSh0ck™]

If only FF can be made to ran in windows just like how it runs in linux that would be great. FF in linux runs pretty smoothly.

[nooooooooo]

Too bad I hate what Firefox 4 looks like...

Me too. Remember, once it's finished your going to be able to make it look like whatever you want. That's why I use Firefox. I have the beta tweaked and all glass with stylish extension, to beautiful now.

^Google Chrome does so too. At least in their 7 Builds.

I stick with Firefox, because the Adblock Plus extension works to amazing lengths unlike the one for Chrome.

does chrome 7 builds crash alot? -peace ;)

no

Try the "canary" build. It's a 7 version that includes an updater built-in, so it always stays current. It's the dev version of chrome, not the chromium unstable versions. One thing I like about the "canary" build is that it will not let you set it as your default browser. I would never use chrome all the time, just when I feel like. Perfect!
