Opera 10 alpha: Compliant and faster--but not fastest

Opera 10 is both Acid3 compliant and faster than previous versions of Opera. Get a hands-on look at the future of the Norwegian Web browser.

A correction was made to this story. See below for details.

Testing Opera 10 alpha confirms it can boast that it's the second browser in development that is fully compliant with the Acid3 benchmarks. It's also markedly faster than Opera 9.62 at processing JavaScript, but it's half as fast as the fastest Web browser currently available.

On both Windows and Mac OS, it was no surprise to see the Acid3 standards test come up 100 out of 100 since that was the big news from Opera Software earlier today. The browser is also three times faster than the current stable release, with the SunSpider Java test clocking in at 5,740.8 milliseconds. That compares very favorably to Opera 9.62, which I benchmarked at 15,468.8 ms, but is still slower than the Firefox 3.1 beta. Mozilla's latest developer build zips in at 2,787.6 ms when running its new TraceMonkey JavaScript engine.

The majority of the changes in this Opera alpha release are aimed at developers. The average user will rarely, if ever, come into contact with them. That doesn't mean they're not important, though, with further support for CSS3. These changes include sourcing fonts, transparency rendering, animation framerates, and two key evolutions in Opera Dragonfly. You can use the DOM inspector to determine the source of traffic, useful for Ajax debugging, and the ability to edit attributes in real-time.

There are three minor but important user-level changes. It's hard to believe that HTML support in Opera Mail was missing before now, but you'll now be able to see all those holiday e-cards within Opera. There's also a spell-checker rolled in for text fields, not just e-mail.

Opera 10 features an auto-install option for updates.

The last new feature, automatic program updates, could be potentially risky. Certainly in Firefox it would likely lead to the disabling of many extensions, although there's not much of a chance of that happening in Opera with its smaller developer community. The bigger concern is one of control: do you choose which version of a program you get to use, or does the publisher of the program? As annoying as Apple's update monitor and nag screen are, they don't force users to update; you can opt out.

It took a little hunting to find, but the default setting in Opera 10 seems to be the more standard notification behavior. If you'd like to tweak your update settings, go to Tools, Preferences, choose the Advanced tab on the right and then Security from the list of options. The Opera update drop-down menu allows you to change the default to "Don't check for updates" or "Automatic updates".

The big news of the standards compliance will only take Opera so far if other browsers match that mark. It'll be interesting to see, as Google Chrome introduces extensibility, whether Opera will go that route or if it'll try to maintain its niche market as a solid and fast out-of-the-box browser. However, Opera 10 was surprisingly stable during a half-day of testing for an alpha release, crashing not even once.

Correction: This story initially gave the wrong name of the Java test I ran. It is called SunSpider.
