LESS LINES OF CODE EXECUTE FASTER THAN MORE LINES OF CODE
Yet, some people still need to see proof:
0. Win7 5x slower than XP
1. Vista: 25% slower than Windows XP
" We did informal tests, booting both Vista and XP on the same hardware, and Vista was between 15% and 25% slower than XP in benchmarks"
2. Inforworld: WInXP slower than Windows 2000
"Waiting for Windows XP"
" as indicated by results of independent testing performed by CSA Research and confirmed by our work in the InfoWorld Test Center. Our tests of the multitasking capabilities of Windows XP and Windows 2000 demonstrated that under the same heavy load on identical hardware, Windows 2000 significantly outperformed Windows XP. In the most extreme scenario, our Windows XP system took nearly twice as long to complete a workload as did the Windows 2000 client"
3. Win2k slower than NT4...
Microsoft looks to bury test results that show NT is faster than Win2000
"Microsoft recently threw around its weight -- and its fat wallet --
to squash an independent testing lab from publishing benchmark results
that the lab ran for InfoWorld's sister publication NetworkWorld. The test
demonstrated that SQL Server 7 runs nearly twice as fast on Windows NT
4.0 than it does on Windows 2000 ."
