I'm gonna recommend my corporation to just drop MS products entirely. There are alternatives. We're getting so sick of all of it.

Microsoft is attempting to write yet another handbook on how to destroy decent software by bloating it with useless and/or inefficient features. Please fix it

So slow when sharing screens using Teams (trying to share Microsoft Business Central)...

CW commented
Teams uses 400-600 MB of RAM even when it isn't being used (all Teams windows closed, task bar icon hidden). This is crazy. For contrast, Skype for Business uses about 50 MB.

Not only is it slow, if switching between "teams" and "chat", even for a moment will reset which Teams room it was in previously, as well as the folder, and any open documents. it seems to default to the Teams room that was opened when Teams last minimised to tray. Then the slow and frustrating experience of navigating back to the correct room and document begins again.

N.B. Teams user voice is where you post ideas that get ignored so the 'issue' can be closed on Microsoft's end.
The highest voted items are all years old and no product changes to address them.

Trying to support this in my org is a nightmare.
User calls in about Teams using up all the memory and all I can tell them is that we're all experiencing the same issue, and that Microsoft has shown no interest in improving the performance.Microsoft needs to be accountable for stuff like this. Countries need to mandate Microsoft to warn its' potential customers of their lackluster performance and they need to be sued for software issues that cause lead to a loss of capital.

As everyone else has mentioned, MS Teams is painfully slow!
-Switching between 'tabs' for example going from 'Chat' to 'Teams' or 'Calls' tab is extremely slow, and take 5-10 seconds
- Scrolling through chat history is equally slow
- Search function is poor, When I search for a message, I can't go to that message (for example, sometimes the message after the one you searched contains the info)
- Memory and CPU usage is insane - 780+MB and 8-10% CPU at idle (I am running a new-ish i7 with 16GB RAM) -

I would also mirror the experience with Teams application being a memory and CPU hog. I have found the web app to be slightly better, not experiencing the typing lag like I do with the desktop app.

This is seriously a issue on Microsoft's part that after 4 years they still have not fixed or addressed this obviously known and well-documented issue. It is absolutely unacceptable for a program to be utilizing over a gigabyte of memory while running, even in the background (which is enabled by default, along with auto-start). For anyone wondering, I would switch to Google Classroom in a heartbeat, but for some reason my school still decides to pay large sums of money to Microsoft every year for an inferior product suite.

At least provide an option in-app to clear the cache instead of asking us to visit a dozen different folders to trash manually.

Still, to this day, a full year after users started complaining about the memory and CPU usage of MS Teams, this product on my laptop consumes 20% of my battery life and 1GB+ of RAM.

All teams processes taking up almost 1.5GB of memory' macOS Catalina 10.15.7, Microsoft Teams Version 1.3.00.28778. I'm having opened just one chat window and help page. That is crazy and needs to be addressed pretty quickly...

In fact, mine is always on 800-1000MB of RAM!
If you like bugs and non-optimized software, Microsoft is for you, it never disappoints you, it's the best bugged software you can get to decrease your productivity!

Looks like windows now has the same performance issues on windows as on a mac. The mac performance issues look to have been outstanding for over 2 years according to the microsoft voice requests pages to fix the CPU utilisation and memory issues. Great to see there is some consistency here. Maybe now Microsoft may fix teams for mac as well.

Seems like there was a severe degradation with the last MS Teams update. I'm on
You have Microsoft Teams Version 1.3.00.33674 (64-bit). It was last updated on 12/14/20.
Teams chat freezes up. Also, other applications, such as Excel don't work properly. MS Teams was using up to 35% CPU in task manager, and CPU was maxed out at 100%. This dropped about 25% after closing my Teams call, but still running slow.
I'm on Windows 10 Enterprise, with Intel(R) Core(TM) i5-8350U CPU @ 1.70 GHz 1.90 GHz... and 16.0 GB of RAM.

I had the same problem as everyone here with random crash because I didn’t have any memory left. I did modify my page file from 1024/1024 to 4096/8192 even if I have 16gb of rams and I didn’t have ANY crash or problem since then with Teams
