Chrome 17, the latest and greatest, is fast. But, then Chrome has long been faster than its competition: Mozilla Firefox, Microsoft Internet Explorer, Opera, and Apple Safari. This latest update though has more than pure speed. It also comes with some new, useful features.
The best of these is security related. Besides such squashing potentially dangerous security bugs, Google now automatically runs checks on executable .exe and .msi files. If the program doesn't match a built-in white list of OK programs, Chrome then automatically checks in with its Safe Browsing site to see if the Website you picked the program is known for of malicious downloads.
If the file isn't from a known source, Chrome automatically sends the URL and IP of the host and other meta-data, such as the file's hash and binary size, to Google. The file is then automatically classified using machine learning analysis and the reputation and trustworthiness of files previously seen from the same publisher and Web site. Google then sends the results back to Chrome, which warns you if you're at risk.
Google also wants you to know that "It's important to note that any time Safe Browsing sends data back to Google, such as information about a suspected phishing page or malicious file, the information is only used to flag malicious activity and is never used anywhere else at Google. After two weeks, any associated information, such as your IP address, is stripped, and only the URL itself is retained."
Don't trust Google? Fine. You can turn Safe Browsing off. Mind you, I think you'd be an idiot to do this. Windows users, in particular, are in constant danger from malware and this is a simple, slick way of cutting down on potential viruses. From where I sit, you're in a lot more danger from malware than you are from paranoia about Google tracking your file downloads.
Another handy feature is what Google calls Omnibox pre-loading. What that mouthful means is that when you start typing a URL into the Chrome's address bar, aka the Omnibox, you'll see various suggestions about what site you might be looking for. That's in been in Chrome for a while Google has taken the next step though. If Chrome's is absolutely sure it knows what site you're going to, it will start pre-loading the site. So, for example, when I start to type in "zd," "plu," or "Fac," Chrome 17 will start loading, respectively ZDNet, Google Plus, and Facebook.
This can have the effect of making Chrome look even faster than it is... so long as it's guessed correctly. In my experience, Chrome gets it right almost every time, but then I tend to visit the same dozen or so sites over and over again. If you visit dozens or hundreds of sites, you'd be unlike to notice any improvement. If it doesn't seem to be working for you, or, worse still, it starts pre-loading the wrong sites so your performance seems worse, you can switch it off by un-checking "Predict network actions to improve page load performance" in Options > Under the Hood.
With that out of the way, let's move to the testing. I'd been running Chrome 17 on my usual mix of PCs. That includes several Linux desktops, including my Linux Mint desktop, several Macs running Snow Leopard and Lion; and a couple of PCs running Windows XP SP3 and Windows 7 SP1. It ran on all my platforms.
On the HTML5 Test, which checks to see how compliant the Web browser is with the HTML5 Web page standard, Chrome 17 scored 374 out of a possible 450. Coming in second was Firefox 10 with a score of 332.
For performance testing, I ran Chrome against the latest releases of Firefox, 10.0, and Internet Explorer, 9.08, on a Gateway DX4710 Windows 7 SP1 test box. This PC is powered by a 2.5-GHz Intel Core 2 Quad processor and has 6GBs of RAM and an Intel GMA (Graphics Media Accelerator) 3100 for graphics. It's hooked to the Internet via a Netgear Gigabit Ethernet switch, which, in turn, is hooked up to a 100Mbps (Megabit per second) cable Internet connection.
Taken as a whole, Chrome remains the fastest browser around. When you include its new features, it's clear to me that Chrome is continuing to be the top Web browser.
