Administrator Tarun Posted July 3, 2009 Administrator Share Posted July 3, 2009 For a good part of Tuesday, the Web Standards Project's Acid3 testing server was offline. With it went 25% of our browser performance testing capacity, which kept us from being able to publish our initial Mozilla Firefox 3.5 performance index as originally planned. As Acid3 started coming back, browsers were posting curiously low scores (for instance, Opera 10 Beta below 100%) that led us to dispute the test more than the browser. Today, however, with the server back online, we're able to give a reliable performance estimate for the first fully stable edition of Firefox 3.5. Earlier this week, some of our readers advised us that 3.5 RC3 would be bit-for-bit identical with the final 3.5, so the scores should come out the same. And if they don't, then something must be wrong with us. No, that's not correct. Many of the scores contributing to our benchmarks, such as individual heats in the SunSpider test, were indeed either the same or within 0.5 ms of the RC3 score. But some of the advances we saw in the final private builds, particularly in DOM handling and regular expression (RegEx) parsing, did carry over into the final 3.5 build after all, for big gains in those departments specifically. That's the thing about speed test profiling: We can see where things change and where they don't. As a result, Firefox 3.5 posted a 9.93 in our performance index on Windows XP SP3. What that means is, this latest browser generally performs nearly ten times better on XP than Microsoft Internet Explorer 7 (the previous version, not IE8) on Vista SP2, which is about the slowest browser you can run (and therefore the one we chose for our index). Similar gains in the same departments were recorded for Vista and for Windows 7 RC. Vista still slows down the browser (any browser) noticeably, making it post a 7.61 index score. While Windows 7 is still a slower platform than XP, it's not nearly the bear that Vista has been: Firefox 3.5 scores a 9.24 in Win7 RC. In terms of speed alone, the new Firefox runs 29% faster in Win7 RC than Vista SP2, and 41% faster in XP SP3 than Vista SP2. On average (taking into account some new and welcome speed gains in the latest Opera 10 Beta), Web browsers run 20% faster in Windows 7 RC than in Vista SP2. Comparing the new Firefox to the one folks were running just last week, by Betanews estimates, version 3.5 runs at 253.8% the speed of version 3.0.11 in Windows XP SP3, 246.5% the older version's speed in Vista SP2, and 254.6% the speed in Windows 7 RC. That averages out to about 251% the older version's performance across the board. Yesterday's release of Firefox 3.5 means that the "Shiretoko" development track, which Mozilla reserves for whatever "the next version" may be, is now devoted to whatever improvements are to be incorporated in the first bug fix release, to be called version 3.5.1. There's no release date or even a forecast for this, because there just aren't that many bugs yet. But we are seeing minor performance improvements in the Shiretoko track over 3.5, including a 9.34 index score for Win7. It also means the "Minefield" development track for 3.6 Alpha 1 undergoes some changes as well, the early results of which indicate that some temporary fixes were made to the JavaScript engine. Performance of the 3.6 Alpha daily build plummeted sharply on all three platforms (with Vista down to 6.48), though this may not be a suggestion that the 3.6 browser will necessarily be slower. Rather, developers may be reverting to older code in the interim, in order to make complete builds for now.

Ultimate Predator Posted July 3, 2009 Share Posted July 3, 2009 Woah, didn't realise the massive speed difference between Firefox and Safari or Chrome. The again, didn't realise the current release of Chrome is so close to Safari, and that the beta Chrome is gonna be insanely fast. Definitely think I'll be checking out Chrome in a min, and might switch to it permanently when they get extensions and if they maintain such speed differences.

Administrator Tarun Posted July 3, 2009 Author Administrator Share Posted July 3, 2009 After the Chrome EULA incident, I'm not going to dare touch it anytime soon. The reason Chrome and Safari are so similar is because they use the same engine known as WebKit. Quote Link to comment Share on other sites More sharing options...

I know that Chrome does a lot of tracking, some of which isn't optional (http://en.wikipedia.org/wiki/Google_Chrome#Usage_tracking), which I certanily don't like. IO probably won't be using it for that reason. Does firefox have similar tracking? Ah, didn't realise. What is Safari like? Heard Apple are a pretty nasty company as well.

Administrator Tarun Posted July 3, 2009 Author Administrator Share Posted July 3, 2009 Never used Safari. I don't really care for any of the Apple product line, the i"Life" or how the people who are in it behave and conduct themselves. http://arstechnica.com/tech-policy/news/2008/09/google-on-chrome-eula-controversy-our-bad-well-change-it.ars http://gizmodo.com/5044871/google-chrome-eula-claims-ownership-of-everything-you-create-using-chrome-from-blog-posts-to-emails Quote Link to comment Share on other sites More sharing options...

Scary stuff, isn't some of it still there as well? Quote Link to comment Share on other sites More sharing options...
Administrator Tarun Posted July 4, 2009 Author Administrator Share Posted July 4, 2009 To be honest I'm not sure, though I wouldn't be too surprised if it was in there in some extent in a reworded method. Quote Link to comment Share on other sites More sharing options...

Eldmannen Posted July 4, 2009 Share Posted July 4, 2009 Interesting diagram. Chrome is very fast. Though, performance varies for different things, scenario and usage. Example, someone can have a fast rendering engine, but a slow JavaScript engine. After the Chrome EULA incident, I'm not going to dare touch it anytime soon. The reason Chrome and Safari are so similar is because they use the same engine known as WebKit. As far as I am aware, it was a mistake because they just copied and pasted it or something. I am glad that people refuse to use software with bad EULAs. Makes me think of EULAlyzer. Quite fun to hear that coming from a Windows user, as Microsoft EULAs aren't particularly known for being permissive or friendly. As far as I am aware, you're not even allowed to publish benchmarks of Vista. There is a fork/version/derivaitive of Chrome called SRWare Iron with better privacy. Sounds like you really don't like Apple! Neither, do I. They do shiny and pretty stuff. They're good at marketing. Pretty on the outside, evil on the inside.

Administrator Tarun Posted July 5, 2009 Author Administrator Share Posted July 5, 2009 I believe the benchmark things were for the betas/RCs, which makes sense. Quote Link to comment Share on other sites More sharing options...
James_A Posted July 10, 2009 Share Posted July 10, 2009 That's a very interesting graph, but you have to be very careful reading it because it is not a pure speed graph. As the reference to the Acid test suggests, it's a combination of speed and accuracy. What it does show, however, is how big a performance hit you take if using Vista. That's definitely a pure speed thing. Quote Link to comment Share on other sites More sharing options...
