The first service pack for Microsoft Windows Vista operating system won’t arrive until early next year, but judging from many experience with a beta of SP1, the update will be more about stability and security fixes than noticeable performance gains.
What is Improved
Many alterations in this service pack, the tested version of 0.275 won’t be obvious to a casual user. You probably won’t notice any interface changes, for example.
Instead, Microsoft says, the service pack beta improves stability, performance, and reliability when reactivating a machine from Hibernate or Suspend mode; enhances device-driver support; increases security; and adds support for new standards such as Extended File Allocation Table (intended to enhance flash storage on notebooks, not desktops).
According to Microsoft, typical load times for the final version should range from 30 to 60 minutes. The installation requires 7GB of free hard-drive space (some of which will be reclaimed after the installation is complete), though the finalized install file itself is expected to be a 50MB download via Windows Update.
In early tests with the beta, some small improvements in boot time on an HP Compaq 8710p Core 2 Duo notebook. Before SP1, the laptop took 1 minute, 51 seconds to boot. After the update, that figure dropped by almost 20 seconds.
Microsoft is also touting improvements in the speed of copying and extracting files, so that also tested a few of those scenarios. Noted that a slight increase in the time required to copy 562 JPEG images totalling 1.9GB from an SD Card to the hard drive of the a fore mentioned HP Compaq notebook.
In another test, Nero 7 Ultra on an Acer Aspire 5630 Core 2 Duo laptop were tested to add files to a disk image. After SP1 installed, the notebook built the disk image about 7 percent faster.
