Google has begun work on a feature to let Chrome load pages before they're needed, the latest instance of the company's relentless focus on Web performance.

The work, described briefly in the Chrome issue tracker, said the project to "pre-load pages in background tabs for 'wicked fast' page loads" is scheduled to arrive in the browser's code base in February. The very early stages of work has begun: support for an eventual option to enable testing the feature through Chrome's "about:flags" interface.

The 1,200 horsepower club has a new member. Hennessey Performance's 2011 Venom GT makes its first appearance at the 2010 SEMA show next week, the same aftermarket and tuner conference at which its prototype was revealed three years ago.

Since then, the Texas-based boutique carmaker has been busy producing what could be described as the Tesla Roadster's much dirtier evil twin. The Lotus Elise/Exige-based supercar has a 6.2 liter V-8 mid-engine that delivers 1,200 horsepower, a top speed of 267 mph, and a 0-60 mph time of 2.5 seconds. Getting to 200 mph … Read more

Most of the time when people mention "benchmarking," they are referring to ways to compare one computer's performance against another's under the same software conditions. While this is useful to find the fastest RAM, quickest hard drive, or any other component that will give you the best bang for the buck, it can also be used to outline when the computer is running slower than expected.

Systems can run slower for a variety of reasons, including full hard drives, connected peripheral devices, large and complex user caches, or also from problems with file and file-system corruption. … Read more

The 2012 Hennessey VelociRaptor APV, based on the new Ford Raptor Super Crew, boasts a supercharged 6.2L V8, with off-road capabilities--and it comes in armored and nonarmored versions.

Windows' disk defragmentation tool is an old workhorse that recent upgrades haven't really improved.

When it comes to graphics performance in OS X, Apple has taken the conservative approach and focused on compatibility and stability in drivers instead of including the cutting-edge and highly tweaked drivers and graphics systems that bring the best quality to performance-related applications like games.

This compatibility-based approach may be good for productivity applications to prevent potential crashes, but has kept Apple behind when it comes to gaming performance. For awhile this was not an issue, but the recent release of Valve's "Steam" client for the Mac along with a few other gaming titles have not only … Read more
