How embarassing — Microsoft commissions teststhat compare Vista and XP, with the goal no doubt being to show howmuch better the new version is. Except that’s not what the test resultsprove.

Principled Technologies Inc., which performed the tests on the vendor’s behalf, showed Vista SP1 actually lagged XPon about 46 per cent of the business-oriented operations it measured.(The gap was 61 per cent on the consumer-oriented tests, but that’s notprimarily what we’re concerned with here.)

Important to note is that XP shone in tests on PCs that had justcome out of sleep mode. In cold boot tests, Vista picked up the pace.Whether that’s enough to trigger massive Vista adoptions is anotherstory.
