Microsoft Teams Development Team Details Performance Improvements Across Platforms

Key summary

The Microsoft Teams development team has released details regarding backend improvements designed to increase speed and reduce resource consumption on Windows, macOS, Android, and other platforms. On PC (Windows & macOS), a new Efficiency Mode has been introduced for devices with lower resources, such as older CPUs or 8GB of RAM or less; this mode improves responsiveness by 20% on low-resource machines, automatically reduces video resolution to save CPU power, and maintains smooth audio processing. For Android, Microsoft created an App Responsiveness Index (ARI) testing suite to identify lag in app usage videos, finding that 60–65% of issues stem from memory problems. Following these findings, Microsoft addressed multiple memory-related issues, resulting in a 40% reduction in slow frame rates compared to the previous year and a 23% decrease in app stuttering caused by garbage collection. Additionally, the loading speed for chat thumbnails that previously appeared late during scrolling was improved by 17%.
