This paper describes the background and methodology for measuring system resume from Sleep (the ACPI S3 system power state) performance on computers running the Windows Vista operating system. This paper describes the phases of the S3 resume process and includes information about the Windows Vista infrastructure that provides accurate measurement of S3 resume times. This paper also demonstrates example methods for measuring S3 resume performance by using tools in the Windows Driver Kit (WDK), discusses steps for measuring and optimizing resume from Hibernate (the ACPI S4 system power state), and provides tips for driver developers to ensure that device drivers support fast system resume performance.
This information applies for the Windows Vista operating system.
