Slow performance and high memory consumption
This may technically be a bug but I'll add this anyway as a blanket item. The performance of the desktop client is just abysmal in my experience.
Clicking around constantly freezes the UI, and typing is painfully slow.
Hi guys! Thanks for submitting this. I totally hear you and have experienced this as well.
The good news is, we’re actively working on this. We recently pushed an update that improved performance when channel switching and scrolling. So this should be considerably better for you.
We’ll continue to make improvements on performance, so stay tuned for updates.
Keep the suggestions coming and thank you for helping us make Teams awesome!
