Firefox 4 preview builds with JägerMonkey JavaScript engine now available for download
I've got the Windows version installed, and I'll admit that I'm not gobsmacked at the moment. The build feels fast, but not noticeably faster than the nightly builds I've used up until this point. Benchmark scores are certainly good -- with the Firefox 4 preview hot on the heels of Chrome 7.0.517.0 on my system (a quick Sunspider run was nearly neck-and-neck between the two browsers).
Even on the Fluid Dynamics sim mentioned in the post from Mozilla's Dave Mandelin ran at a higher FPS in Chrome.
Maybe my system is having some issues, though -- so let us know! Grab the Firefox 4 JägerMonkey preview build for your platform and tell us how it compares to other browsers!

I still get lower scores on SunSpider with Chrome 6 than Firefox 4 with JagerMonkey.

That's all fine and dandy... but does this beta/nightly build still suffer from memory leaks and slowdowns in general like the 3.6.x versions do?

How does JägerMonkey affect performance numbers of http://service.futuremark.com/peacekeeper/index.action and http://dromaeo.com ?

Matt: They're not finished. They've reached a milestone of being within 20-30% of chrome. This may vary from machine to machine. At the rate they're going, they'll reach parity before final.
Crazy Serb: That's a stereotype from the pre-Firefox 3.0 days. Look at any respectable benchmark results that compares Firefox to any other browsers on memory consumption. Firefox always wins. Normally when people compare browsers, they do it in a very unfair way. Like use browser A for a couple hours and then open browser B for a couple minutes, reopening the tabs from browser A in browser B. Then when they open Task Manager they cry Bloat! or Memory leaks. Uh, no... memory cache. Sure, some of it could memory leaks but this is true for all browsers.

Could post a ton more but the commenting system only allows 3 urls.

I know this may sound like a stupid question, but do the Jaegermonkey nightlies get installed through Help-> Check for Updates? Or do you have to download them from that site?
