All of us got a glimpse of Windows 8′s performance with the launch of Windows 8 Consumer Preview.It’s Fast and Fluid with a refreshingly new Metro UI and for what we all know its Faster than its predecessor Windows 7,thanks to improved memory management and other new improved features like Hardware Acceleration etc.
Recently PCWorld Tested the Windows 8 Consumer Preview and Windows 7 through the WorldBench 7 Tests.In all the tests performed comparing both the operating systems Windows 8 outperformed its predecessor by a good margin.In the worldbench 7 test Windows 8 fared 14% better than Windows 7 which is a huge margin.

The second test was for the Startup Time,the results are quite evident that Windows 8 is much more lighter and faster than Windows 7 when it comes to Starting up the system.The average start up time for Windows 8 consumer preview was around 37 seconds,while that of Windows 7 was around 56 seconds,while the actual startup time to reach the Start Screen of Windows 8 was around 24 seconds.These were the results for a normal Hard Disk Drive,so if you are going to use a Solid State Drive the startup time would improve drastically.

The next Test was the Web Performance Test, this test measures the system rendering performance for the dynamic Web content, which includes JavaScript and HTML 5. Browsers used were Internet Explorer 10 in Windows 8, and IE 9 in Windows 7.The results clearly indicates the performance gain of Windows 8 courtesy hardware acceleration,with the Frame rate almost 40-50% better than Windows 7′s browser.

So far so good for the Windows 8 Consumer Preview baring the lone Office Productivity test in which it was inferior to Windows 7,but considering that it’s not the final release of the upcoming operating system we can give that a benefit of the doubt and surely the performance would only get better in the final release.
Windows 8 is expected to hit the shores by the final quarter of the year with x86 as well as ARM architecture with devices slated to be released by multiple manufacturers in the holiday season.
