Nice work Mozilla. Sometimes I wonder why we give so much importance for 1-2 second page load / javascript improvements. Does average user really care about 1-2 second difference?

#32Congrats Mozilla on the release! Odd title though for this post, for where is the "everyone"? The link shows comparisons to previous versions of Firefox, not other browsers. One thing I hope they fix before final release though is the constant CPU usage when you have many tabs open. I thought the Panorama feature was supposed to address this. It's currently idling at around 25% CPU for me, and no, unfortunately I can…
> Odd title though for this post, for where is the "everyone"? The link shows comparisons to previous versions of Firefox, not other browsers. http://arewefastyet.com/ Sunspider’s not a very good benchmark; more interesting to me is that they’re nearly even with V8 in V8’s own benchmark. Though I wonder why they can’t backport TM, or at least a subset, to 3.6; is Firefox so monolithic that improvements to the scripth…

So cutting response times by a second from say two seconds to one second changes the percieved delays from barely tolereble to barely noticable, which is unually beneficial for interactive apps.

#34All I want is a light weight FireFox .
Of course, SeaMonkey is pretty fast nowadays too.

#35I would use 4.0 Beta full-time if Firebug and Yahoo's Delicious extensions were updated. The memory utilization is great just like Firefox 3.6. Compare sometime the memory utilized while running many tabs in Chrome vs. Firefox over a prolonged period of time. Update: I found Firebug has an alpha release supporting Firefox 4. http://getfirebug.com/releases/firebug/1.7X/

#37Browsers keep improving JS speed, but is there an upper limit to how fast it can be? How far off is it from something like C ?
JS speed has improved so much recently due to optimisations like JIT (Just In Time compiling). There will be an upper limit eventually but we haven't hit it yet. It's damn fast but still a high-level interpreted language - time is taken for a program in the browser to compile it on the fly and run. It wont hit the speed of well written C code, but most things don't need that speed anyway.
Here are the results: http://shootout.alioth.debian.org/u32/performance.php?test=r...
Also worth noting that TraceMonkey isn't too far behind. Does anyone know why the JS engines, especially V8, are performing so well on this test?
P.S. Here's how V8/TraceMonkey stack up for all the tests: http://shootout.alioth.debian.org/u32/which-programming-lang...

#38It's probably about perception; maybe the browser should show a window even if it's not really ready (and maybe there is a problem with plugins and add-ons that need to initialize themselves, etc.)
Anyway, how is FF4b7 doing in this regard...?

#39Browser vendors talk about benchmarks all the time but what really matters to me is startup and closing times; here Chrome really shines and FF3.6 is slow as hell. It's probably about perception; maybe the browser should show a window even if it's not really ready (and maybe there is a problem with plugins and add-ons that need to initialize themselves, etc.) Anyway, how is FF4b7 doing in this regard...?

I was browsing the language shootout the other day and came across the page for the regex test. I'm not sure how it's doing it or if something is wrong with the test but V8 is outperforming everything else, including C. That's the only test it leads though.
