Android 16 has a new trick to speed up app installation

Android 16 introduces a feature called cloud compilation, which enhances app installation speed by shifting the compilation process from the device to the cloud. This feature allows application artifacts to be loaded directly from files downloaded via the Google Play Store, rather than being generated on the device. It is particularly beneficial for low-end devices that struggle with processing power or storage speed. The Android Runtime (ART) uses a tool called dex2oat to convert APK’s .dex files into application artifacts, which include .vdex, .odex, and .art files. Cloud compilation retrieves these artifacts from a new format called Secure Dex Metadata (SDM), ensuring application integrity while expediting installation. However, the feature is not yet operational as Google needs to configure the Play Store to generate these artifacts for use during installations.

Microsoft’s word-soup has made Windows 11 updates noticeably quicker via the ‘parallel processing of component manifests’ complementing ‘the parallel hydration of newly serviced components using reverse and forward differentials’

Microsoft's Windows 11 24H2 update has significantly improved update installation speed, with internal tests showing a 44 to 46% increase compared to the previous 22H2 version. Restart times during updates are also 34 to 40% quicker, depending on hardware. The enhancements are attributed to technical innovations such as parallel processing of component manifests and caching information about update packages, which utilize CPU capabilities more effectively. Additionally, some update packages have been reduced in size by up to 200 MB.

Microsoft Is Finally Making Installation of Windows Updates a Breeze

Steve DiAcetis from the Windows Fundamentals team announced that the upcoming Windows 11 24H2 update will enhance the update installation experience by streamlining the process, resulting in reduced installation times, quicker restarts, and lower CPU usage. Initial tests showed a 45.6% faster installation time, a 39.7% improvement in restart times, and a 15.3% reduction in CPU usage when upgrading from Windows 11 22H2 to 24H2. A separate evaluation on a device that hadn't received updates for 18 months revealed a 43.6% faster installation speed, a 33.5% quicker restart, and a 25% reduction in CPU usage. Additionally, the size of feature updates has been reduced by approximately 200 MB by integrating system applications into monthly updates, while other applications will require updates through the Microsoft Store.

Microsoft Is Finally Making Installation of Windows Updates a Breeze

Steve DiAcetis, Principal Program Manager Lead at Microsoft, announced that the upcoming Windows 11 24H2 update will significantly improve the update installation experience by reducing installation times, restart durations, and CPU usage. The update will provide a 45.6% faster installation time compared to Windows 11 22H2, a 39.7% reduction in restart time, and a 15.3% decrease in CPU usage. Tests on a PC that hadn't received updates for 18 months showed a 43.6% increase in installation speed, a 33.5% faster restart time, and a 25% reduction in CPU usage. The servicing stack for Windows 11 22H2 is comparable to 23H2, indicating that improvements in 24H2 may apply to earlier versions as well. Feature updates will be approximately 200 MB smaller, achieved by integrating system applications into monthly updates, while other applications will be updated through the Microsoft Store.

Windows 11 24H2 makes PCs faster with reduced CPU usage for Windows Update

Windows 11 24H2 introduces enhancements to the update process, including "checkpoint cumulative updates" to reduce the size of monthly update packages and improve overall PC performance. Key improvements include: - Faster installation time: 45.6% faster on well-maintained devices and 43.6% faster on outdated devices. - Reduced restart time: 39.7% faster on well-maintained devices and 33.5% faster on outdated devices. - Lower CPU usage: 15.3% less on well-maintained devices and 25% less on outdated devices. - Smaller feature updates: Approximately 200 MB reduction in download size, with conditional app downloads for only outdated or missing apps. - Techniques used to accelerate updates include reverse and forward differentials, caching parsing results, and dynamic RAM allocation. Comparative tests showed significant advancements in update efficiency, with improvements in both installation speed and resource usage. Microsoft has also separated store app updates from core system updates for a smaller overall footprint.
