Andrew Cunningham writes via Ars Technica: If you or your employer uses Microsoft Teams for communication, good news: Microsoft is releasing a fully rewritten version today for Windows PCs and Macs that promises to run faster while using fewer system resources. A preview of this app was originally released for Windows in March, but the final release covers all types of Teams instances, re-adds support for features like breakout rooms and third-party app support, and supports macOS. The new Teams app is notable for improved performance and reduced disk space usage, especially when running on Windows PCs. Microsoft says that the reformulated version of Teams is “up to two times faster while using 50 percent less memory” on Windows systems. That sound you hear is old and underspecced work PCs in offices around the world breathing a sigh of relief.
Microsoft credits its Edge WebView2 backend with helping improve performance and reduce disk usage on Windows. That’s possible partly because WebView2 can use many of the same system files and the same runtime as the Edge browser built into Windows 10 and Windows 11. The older Teams app used the Electron framework, also used by communication apps like Slack and Discord. Though Electron and WebView2 are based on the Chromium browser engine, each Electron app includes its own self-contained version of the browser files, which all must be stored and updated separately.
