- Includes improvements to Windows Superfetch™ that help to further improve resume times, in many environments.
- In specific scenarios, SP1 reduces the shutdown time by a few seconds by improving the Windows Vista utility designed to sync a mobile device.
- Improves the time to resume from standby for a certain class of USB Hubs by approximately 18%.
- Improves network connection scenarios by updating the logic that auto selects which network interface to use (e.g., should a laptop use wireless or wired networking when both are available).
- Improves the performance of the user login experience on corporate PCs outside of corporate environments (e.g., a corporate laptop taken home for the evening), making it comparable with PCs within the corporate environment.
- Reduces the time it takes to return to the user’s session when using the Photo screensaver, making it comparable to other screensavers.
- Removes the delay that sometimes occurs when a user unlocks their PC.
- Improves overall media performance by reducing many glitches.
- In SP1, PC administrators are able to modify the network throttling index value for the MMCSS (Multimedia Class Scheduling Service), allowing them to determine the appropriate balance between network performance and audio/video playback quality.
- Windows Vista SP1 includes a new compression algorithm for the RDP (Remote Desktop Protocol) that helps reduce network bandwidth required to send bitmaps or images via RDP. The compression, which can be selected by administrators via Group Policy settings, is transparent to all RDP traffic, and typically reduces the size of the RDP stream by as much as 25-60%, based on preliminary test results.
- The Windows Vista SP1 install process clears the user-specific data that is used by Windows to optimize performance, which may make the system feel less responsive immediately after install. As the customer uses their SP1 PC, the system will be retrained over the course of a few hours or days and will return to the previous level of responsiveness.
- SP1 addresses a number of customer performance concerns with new print driver technologies, including XPS-based printing.
