On the individual tests, the benchmark results were generally within a few percentage points of each other. One notable exception, however, was Nero 7 Ultra Edition, where Windows 7 made significant improvements, ranging from a 12 percent speedup to a 26 percent speedup, depending on the PC we used in our tests.
The test involving WinZip, another hard-drive-dependent task, also showed marked improvement under Windows 7. We also measured a noteworthy 7 percent speed increase in our Autodesk 3ds max 8. In contrast, however, each of the systems took slightly longer to perform the tests in Microsoft Office and Firefox when they were running the new operating system than when they were running Vista. We saw similar incremental performance improvements on our portable test PCs as well.
In our WorldBench 6 Nero tests, Windows 7 showed big improvements. Performance nearly doubled on average over Vista, which indicates that the new OS enhances hard-disk performance. Lower time equals better performance. Windows 7 makes big gains in disk performance, however. For example, in our hard-disk-intensive WorldBench 6 Nero test—in which we create a series of images of an optical disc and then save them—every PC we tested showed an improvement.
In our comparison of the bit versions of Vista and Windows 7, the IdeaPad Y performed the test twice as quickly with the newer OS. Meanwhile, our Gateway T was almost two and a half times faster, going from a time of seconds to complete the test on Windows Vista to a time of seconds on Windows 7. We had noticed a similar speedup on disk-intensive tests in our earlier evaluation of the Windows 7 release candidate; such gains may be due to updated hard-disk drivers under Windows 7.
One particular result worth noting: In our testing, the bit versions of Vista produced poorer disk performance than the bit Vista editions did. That explains the larger WorldBench 6 score advantages over Vista that we saw from bit Windows 7 compared with bit Windows 7. Microsoft says that in Windows 7 it changed the way the operating system handles starting up processes when you boot your computer.
For some processes and services, Microsoft employs a scheme called trigger-start services. These are system services and processes that under Vista would have started up when you booted your PC, but now kick in only as needed.
Reducing the number of services that start at boot is supposed to reduce boot-up time. Shorter times indicate better performance. In our boot-up tests using one desktop and one laptop, though, we saw mixed results. Windows 7 Home Premium also the bit edition took slightly longer, averaging On our HP Pavilion at test desktop, the outcome was reversed.
The bit edition of Windows Vista Ultimate Edition booted in In subsequent testing, however, we discovered that the bit version of Windows 7 exhibited a similar speedup on our HP desktop, going from an average of Windows Vista.
