Service Pack 2 for Windows XP

摘要

The release of Service Pack 2 (SP2) for Windows XP marks a significant step forwards for Microsoft Windows. Specific features such as its support for NX processor instructions and the enormous list of OS fixes were not tested, but are reasons to upgrade in themselves. We tested SP2 on a low-powered machine, representative of an average corporate workstation, rather than a high-end system. The impact in performance was immediately apparent: benchmarks run before and after installing the service pack showed a performance hit of around ten percent.
