Competition in the browser space breeds better performance. And with Google getting into the browser game with Chrome, all of the developers have stepped up their game. With that in mind, we decided to survey the current browser landscape on Mac OS X to see which offers the best JavaScript performance. Given that Chrome for Mac OS X has yet to hit 1.0, we decided to go with the latest nightly builds for both it and Safari (WebKit), as well as the latest Mozilla alpha (3.6a1), Camino beta, and Opera beta.
Late last week, CNET declared the latest developer preview release of Chrome 4.0 for Mac OS X was the 'fastest OS X browser,' citing SunSpider benchmark performance that was 34 percent better than Safari 4.0.3. The 'fastest browser' competition is always evolving: last summer there was a heated race for the title of Mac OS X browser speed champ. Our own testing reveals that the current alpha builds of Chrome edge Safari 4.0.3 slightly, but WebKit nightly builds are still out ahead of the pack.
First, it's important to note a couple of things. Safari, Apple's Web browser, is built using the open source WebKit HTML and CSS rendering engine and the Nitro (n?e SquirrelFish Extreme) JavaScript engine. The WebKit team releases nightly test builds of WebKit + Nitro called, well, WebKit. Google's Chrome browser also uses WebKit for rendering, but uses its own V8 JavaScript engine. The open source project behind Chrome is called Chromium, which also releases regular alpha test builds. CNET only compared one of these alpha builds of Chromium to the shipping version of Safari. We thought a comparison with a Safari alpha—essentially, a WebKit nightly—would be more fair. And since Mozilla is shooting for major JavaScript improvements for Firefox as well, we compared the latest shipping and alpha versions of Firefox, which use the Gecko rendering engine and TraceMonkey JavaScript engine.
Here's the test bed: a 2.0GHz Core Duo (32-bit) MacBook with 2GB RAM and Mac OS X 10.5.8. All the latest versions of the most common Mac OS X browsers were installed, including Safari 4.0.3, WebKit nightly build 47388, FireFox 3.5.2, Firefox 3.6a1, Chromium build 23572, and for good measure we included Camino 2.0b3 and Opera 10b3. The system was rebooted, each browser was loaded separately, and run through the SunSpider 0.9 JavaScript benchmark three times in succession. The run times were averaged, though we noted very small variations in execution time.
From the results we can see a couple things. First, Firefox 3.6 will definitely have speed gains due to TraceMonkey improvements—our test showed a 12 percent gain on Mac OS X. Second, these early builds of Chrome, and its V8 JavaScript engine, do in fact edge out Safari 4 ever so slightly. Our testing revealed a 4 percent advantage, far from the 34 percent that CNET claimed. And last, nightly builds of WebKit are faster still—19 percent faster than Safari 4, and 15 percent faster than the latest Chrome alpha. These WebKit results echo those measured by readers who posted SunSpider results in our forums.
Honestly, we'd call the 4 percent difference between shipping Safari and alpha Chrome imperceptible, and we wonder if the more significant advantages of WebKit nightly builds would be noticeable either—we're talking about a tenth of a second difference on a rather lengthy benchmark. In real-world use, we don't think users would notice except for the most demanding JavaScript-heavy sites.
Better still, Safari 4 running on Snow Leopard promises a 50 percent speed boost when running in 64-bit mode (we'll need a new MacBook to test that next month). And, Chrome for Mac OS X is still a long way from being ready for daily use—the versions currently available aren't even close to beta status, much less a stable release.
We've noted in the past that browser performance includes a number of factors, such as network latency and HTML and CSS rendering, and there are even tricks that can influence the subjective impression of speed. But, if we're going to compare alphas to alphas (pun intended), then WebKit is still the reigning JavaScript speed champion.
macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.
All-new Interface
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.
Widgets
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
Safari Extensions
With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.
Webkit Mac Os
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.
Machine Learning
With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.
Mac Catalyst
Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.
User privacy on the App Store.
Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
