Report: Benchmarks Show Windows 7 Pre-Beta to be Bloated, With Compatibility Issues

According to InfoWorld, in terms of basic system design, Windows 7 is shaping up to be a OS X like release, in that it is only a minor iteration over Windows Vista, with little change in performance.

Looking first at the kernel, both Vista and Windows 7 M3 (Milestone 3, the other name for the pre-beta) featured 97 to 100 processes. The system process also consumes a similar amount of memory to Vista, according to the writer. He states, "This was not "MinWin," the mythical, streamlined new Windows kernel that promised a clean break with the bloated Vista... In fact, as I worked my way through the process lists of the two operating systems, I was struck by the extent of the similarities."

The results were that Windows Vista actually beat Windows 7's pre-beta by 5 percent in database tasks, while Windows 7 scraped by with a 2 percent win in workflow tasks.

The memory usage during testing was remarkably similar -- 637MB for Vista and 658MB for Windows 7. The thread count was also very close -- 712 for Windows 7 versus 810 for Vista. InfoWorld's Randall Kennedy sums up his conclusions, stating, "In a nutshell, Windows 7 M3 is a virtual twin of Vista when it comes to performance. The few minor variations I observed during comparative testing are easily explained away by slight tweaks to the kernel (such as the aforementioned MDAC changes); they certainly don't indicate a significant performance overhaul."
