Microsoft is working to speed up boot times for Windows 8.

“Few operations in Windows are as scrutinized, measured, and picked apart as boot,” Gabe Aul, a director of program management for Windows, wrote in a Sept. 8 posting on Microsoft’s Building Windows 8 blog. The goal with Windows 8, he added, was to create “a new fast startup mode that works as a hybrid of traditional cold boot and resuming from hibernate.”

In order to accomplish that, Windows 8 hibernates the kernel session instead of shutting it down. When the computer is booted back up, the kernel data saved in the hibernation file (hiberfil.sys) can help restore contents to memory faster than with a full system initialization. “Using this technique with boot gives us significant advantage for boot times,” Aul wrote, “since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70 percent faster on most systems we ve tested).”

Microsoft has also added a multi-phase resume capability to Windows 8, which is able to use all of the cores in a multi-core system in parallel, to split the work of reading from the hiberfile and decompressing the contents.

What does mean for your average user? In a video included with the blog post, a Windows team member (identified onscreen as Emily Wilson, program manager for the Kernel Platform Group), activates a laptop loaded with Windows 8. It takes a little over eight seconds, from the time she hits the power button, for Windows 8’s colorful tiles to appear. Just to ensure the laptop s starting from a zero-power state, she inserts the battery before turning on the device.

Although Windows 8 will most likely appear sometime in 2012, Microsoft is already ramping up marketing and outreach for the next-generation operating system. For weeks, the company has offered glimpses of the developing features and user interface via its official Building Windows 8 blog.
