Apple intros Safari 5, claims speed edge over Chrome

updated 06:45 pm EDT, Mon June 7, 2010

Apple adds greater HTML5, extensions support

Apple in a low-key evening update unveiled Safari 5, its first major update to the browser in the year. The release, now available, is a major speed boost and runs JavaScript 30 percent faster than Safari 4; it's also about three percent faster than the just-finished Chrome 5.0. It also uses better caching and DNS prefetching to save more data and load pages faster.

Also new are a handful of important features: the release is the first to support extensions for growing the functionality beyond the core browser. Safari Extensions works on CSS, HTML5 and JavaScript. Developers get access to Extensions Builder, a tool that helps create and package add-ons. Apple claims a certain layer of security and requires that all extensions be signed, although it didn't say if it would have any review process like with the App Store.

Safari Reader is equally new and helps optimize content for viewing pages without distractions. Bing has been added as a third search option, and several HTML5 features have come onboard: geolocation, draggable items, Ruby and WebSocket are some of the options.

Apple is launching Safari 5 as a free download for Mac and Windows; it is available now.

    Doesn't work on Safari 5 pg

    Went to the Safari 5 web page ( using Safari 5...and the headline is wacked! Might not be a Safari 5 issue; instead, it appears to be bad HTML code w/ a text line overlapping.

    Still, the irony!

    Guinea pigs?

    Anyone know if existing plugins work still? Like Glims, SafariStand and SIMBL?

    Claims are True

    So far the claims are true. It is a lot faster than Safari 4. I cannot compare to Chrome.

    If a few of the extensions that I use for Firefox are developed for Safari, I will seriously consider switching over. Right now there are a couple of Firefox extensions that I can't live without - the main one being NoScript. If the developers of that extension make a Safari version, I will be all over it.....(fingers crossed)

    I'm using it

    faster sounds good to me, I have it installed, and I'm using it right now, so far so good.

    A Swarm of Androids

    But does it use a JIT compiler to speed the drawing of little Androids swarming over your screen? That surely is the only fair test of a browser's javascript speed.

    Not sure about anyone else, but Safari 5 seems considerably slower for me. I've got to wait several seconds before it even starts to think about loading pages. "Sluggish" is the best word I can come up with to describe it.

    Did some benchmarks against Chrome. Faster in Sunspider, slower in Peacekeeper and V8.
