Let's hope it doesn't get its speed using 100% CPU on all cores.
Maybe its just me
Even my own browser based code editor that I know contains lousy code works well enough on my old Duron based test machine.
Call me when it's faster than Opera...
in not just Sunspider, which a wide range of benchmarks and real-world browsing situations, as other benchmarks put Firefox 4 massively behind Chrome and Opera.
What other benchmarks?
Hence shouldn't it be the yardstick applied to such trials?
(unfortunately) no one uses Opera.
Which makes this news farcical.
My car is also the fastest car in the world. I tested it myself against a Sinclair C5, a Mini Metro running on most of it's cylinders, and a Fiat 500.
I couldn't lay my hands on a Enzo, so I didn't bother testing it against that.
Yes, true enough, if by "no one", you mean "140 MILLION Opera users and growing."
In other words...
...half the TOTal population of the U.S.?!?
Good results, but note shell only
It is important to remember on most websites that without user interaction the content is largely static. Typically things only happen when a) the page is first loaded, or b) the user does something like mouseover or click on an element which has attached JS. When either of these things happens, the performance of is affected by JS, DOM, CSS, rendering API, layout, native event model, operating system, context switches etc.
JS is an important component in this performance but in many cases the browser would spend a lot more time in the layout engine or the DOM code. The JS would just be a little glue which creates an element and sticks it in the document, or twiddles an attribute etc.
Running from the shell is still a good test since it eliminates the other noise. I expect in practice that improving the JS engine would result in subtle improvements. The biggest winner is probably the browser itself since Firefox uses a lot of JS in its UI. Sites that drag in a lot of JS during startup (e.g. GWT, Dojo etc.) probably benefit a lot too.
At this rate
It'll be done before it starts in another 3 months' time
This only applies to x86 at the moment, 64bit lags a little behind.
However, the real problem I've had with FF4b6 isn't speed on js heavy sites, it's stability. If they sort this out then they'll be on to a winner.
I don't know about anybody else, but I've never really had any browser speed problems. And if I had I don't think the tiny lead that Firefox now has over the competition (until next week, no doubt) would induce me to change.
Indeed it is such a tiny advantage that I can't believe Mozilla are shouting about it. Basically the advantage is so small that all three browsers are, in effect, at the same level. As such Mozilla are basically saying "Look how great we are, we've caught up with the competition and we're just as good as them now." Not much of an advertising coup is it? "Buy a Vauxhall, it's just as good as the competion in some areas."
is less of an issue than other factors in the environment. Only time mine is slow is when it is waiting for one of the damn Facebook.static pages to finish uploading its data to my pc. And I'm running the current standard install for FF, not the beta.
pure JS speed isn't really important on regular websites, but to advanced web-apps and especially games... particularly with HTML5. Decent games will be more viable in pure JS/HTML5 at this time, and need performance to compete against Flash.
People are missing the point
When will El-Reg report this then?
As clearly vendor benchmarking is the flavor of the month.
If you can't beat them...
"This new method JIT compiler uses the Nitro assembler from Apple’s open source WebKit project, the same assembler used by Google Chrome and Apple Safari."
In other words, Mozilla couldn't beat them, so they joined them!
KTguju: so do you have 'chrome' on your mobile???
you are missing the point - the article is talking about DESKTOP computers... the only reason Opera on mobiles is so popular, is that the competition is so bad!!!
most guys running a new pc will have no problem I guess - but those on a budget, with an old P4 will notice how sluggish FF is against Opera - you dont need benchmarks to see it!
the big problem with Opera, is the bad attitude of the managers - they remove good features that very old users love, and when we complain, they just ban us for disturbance!! this and a refusal to build in website compatibility or aggressively advertise, is why it stays almost unknown or given a bad rep...
