Thank you for your feedback. Our performance team is working on improving the overall performance of the Windows client. We expect to see performance jumps in the latest version of Electron rolling out (Electron 10).

On Windows 10, the Teams Client is slow and actually slows down the overall performance of my entire system. This is on a Surface Pro 3 iCore 7. The Slack client runs about twice as fast and does not affect the overall performance on my system
