Safari Beats Firefox at Rendering Speeds
Safari Beats Firefox at Rendering Speeds
by , 9:15 AM EDT, June 23rd, 2008
Apple's Safari 3.1.1 Web browser is outperforming the new Firefox 3 browser when it comes to JavaScript rendering, and both clearly beat Microsoft's Internet Explorer. According to tests performed by Zimbra, the version of Safari 4 that's available to developers performs even faster, and there's still room for Apple to experiment and improve even more.
"We had high hopes that FF3GA would at least match Safari 3.1.1 in order to contend with Apple?s Safari 4 just around the corner. Infact that graph is simply those tested in our browser war series; the WebKit nightlies (engine for SF4) deliver a knockout blow," the Zimbra report said. "And it?s not just our favorite testing software that shows this; we use OpenQA Selenium which allows us to nicely calculate time rendering a page while navigating the Zimbra AJAX web-client."
Safari 4's impressive speed boost comes in part from Apple's decision to adopt the SquirrelFish JavaScript interpreter. The WebKit project claims the SquirrelFish engine is 1.6 times faster than the engine in Safari 3.1.
The Zimbra test results show that Safari can hold its own against other Web browsers, and that the competition has some work to do to keep up with Apple.
Observer Comments
You don't speak for me or anybody else I know. Safari isn't even close to having the same features I need (Adblock, Flashblock, Canadian English Dictionary, Japanese Dictionary, Rikaichan; all for free I might add). In fact, it's positively a liability in the large company I work for.
I'll reiterate, it's a good default browser. When you need heavy lifting Firefox is a good choice. As for render speed, well, I can wait the extra second or two (at most).
rpaege: There are add-ons for Safari, too, there's just no centralized location for them or standard interface for installing them like with Firefox. SafariBlock and SafariStand have Adblock and Flashblock covered (and then some), which is the most important thing for me. Of course the selection is nowhere near as wide as with Firefox, but it's not like it's completely closed up. As a developer I find it easier to make Safari add-ons, to be honest.
Personally, I don't use either as my primary browser anymore. I use iCab, which is WebKit-based like Safari. iCab has probably the most robust built-in feature set of any browser (with the possible exception of OmniWeb, which I haven't tried in a while).
Firefox 3 is my secondary browser. It's good. Firefox 2 was good, too. But somehow I've never wanted to replace my WebKit-based browsers (previously Safari, now iCab). Since I moved from Safari to iCab, I use Firefox less and less.
I have a question: do the speed comparisons really just apply to Safari and Firefox, or all WebKit-based browsers and all Gecko-based browsers? I usually assume any browser with the same engine will have pretty much the same performance. But maybe Apple's doing something special with Safari. I don't really know.
