Notable Changes in Windows Vista Service Pack 1 Release Candidate
Microsoft published a list of „improvements” in the upcoming Windows Vista Service Pack 1. A few „high”lights:
- Significantly improves the speed of moving a directory with many files underneath.
- 25% faster when copying files locally on the same disk on the same machine
- 45% faster when copying files from a remote non-Windows Vista system to a SP1 system
- 50% faster when copying files from a remote SP1 system to a local SP1 system
- Improves responsiveness when doing many kinds of file or media manipulations. For example, with Windows Vista today, copying files after deleting a different set of files can make the copy operation take longer than needed. In SP1, the file copy time is the same as if no files were initially deleted.
- Improves the copy progress estimation when copying files within Windows Explorer to about two seconds.
- Addresses a problem that caused a delay of up to 5 minutes after boot with specific ReadyDrive capable hard drives.
- Improves the effectiveness of a Windows ReadyBoost device in reducing the time to resume from standby and hibernate by increasing the amount of data stored in the ReadyBoost device that can be used during a resume cycle.
- Includes improvements to Windows Superfetch that help to further improve resume times, in many environments.
- Reduces the time it takes to return to the users session when using the Photo screensaver, making it comparable to other screensavers.
- 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.
