Generational Windows Multicore Performance Tests
snydeq writes "Windows XP, Windows Vista, and (soon) Windows 7 all support SMP out of the box, but as InfoWorld's Randall Kennedy notes, 'experience has shown that multiprocessing across discrete CPUs is not the same thing as multiprocessing across integrated cores within the same CPU.' As such, Kennedy set out to stress the multiprocessing capabilities of Windows XP, Windows Vista, and Windows 7 in dual-core and quad-core performance tests. The comprehensive, multiprocess workload tests were undertaken to document scalability, execution efficiency, and raw performance of workloads. 'What I found may surprise you,' Kennedy writes. 'Not only does Microsoft have a firm grasp of multicore tuning, but its scalability story promises to keep getting better with time. In other words, Windows Vista and Windows 7 are poised to reap ever greater performance benefits as Intel and AMD extend the number of cores in future editions of their processors.'"
No matter how Windows is coded and designed is the problem really the DRM or Microsofts implementation of it?
How do you know? Do you have the source code to Windows Vista?
Everyone I've seen that blames "DRM" for Vista being slow has no idea what they are talking about, and are just going "Vista has DRM and is slow, therefore it must be slow because of DRM".
Correlation is not causation people!
