Vista SP1 performance is not as expected, no advantage over RTM version

        Xpnet tested the performance of Microsoft's Vista
+SP1 and published relevant test results. From these results, fans of Vista
may be somewhat disappointed.
The test results show that the performance of Vista
+SP1 is not higher than that of Vista
RTM. Please see the figure below for their performance comparison.

It seems that SP1 is not a panacea, or the main goal of SP1 is to improve system stability rather than performance. In addition, SP1 is still in a candidate release and does not fully reflect the performance of the final SP1.
