Teams Meetings appear to take a lot of CPU (avg 32%)
When running a Teams Meeting on my Surface Pro i7 (2017), my screen-sharing, video meeting used about 30-32% of my CPU constantly. This seems different than Skype for Business. My battery life went from 100% to 35% over the 2 hour meeting.
Thank you for your reports. We are aware of recent performance issues with Microsoft Teams meetings, especially on laptops and when using external monitors. The team is working to resolve these issues.
In the meantime, please find troubleshooting information here: https://docs.microsoft.com/microsoftteams/troubleshoot/known-issues/teams-slow-video-meetings-laptops-4k.
We have this issue only on dual Core Devices...
But still more the required System Specs
corresponding github issue:
Whenever I share my screen in Teams, all other programs become more or less unusable! E.g. just opening a page in Edge takes a minute or so.
This is on a new and powerful Dell laptop with external monitor (both internal and external monitor at 1920x1080 resolution).

This has now been an ongoing issue for _three years_. If anything it has gotten worse over the last months. Performance in Microsoft Teams is abysmal.

I have a brand new Surface Book 3 and now not able to use my camera for Teams meetings because of this exact issue.
CPU running to 100% when using external monitors and camera. Switching off my own camera and the CPU goes down to 10-ish% and everything works. This is a critical error as Teams for me, with my brand new Surface Book 3, is not working.
Can also mention that it worked perfectly fine with my previous Surface Book 1.
Happy to help if you want more information.
On a mac and have exactly the same issue of slowness of the machine during a teams video call. Basically cannot present anything anymore while I have my camera turned on. As soon as I turn off my camera it all works fine. I could understand if I were using a fancy backdrop on video but only use the raw video or the blurred effect. Either way makes no difference to the performance issue. When I started using teams a year ago it was all working fine but seems to be getting worse with each new release or update. Used to be able to use onenote for meeting notes now back to pen and paper due to this issue as cannot use onenote while my video is on during a teams call.

This is not happening with Surface devices only; I am experiencing the same with a Lenovo P52 Workstation laptop (We are talking about high specs computers here, with Intel Xeon 6 cores and 64 GB ram). When video enabled or sharing screen the system performance is painful, and when we try to share screen while solving something together it is so frustrating.
By the way... I have 3 monitors.
Teams is using most of my processor (>30%) and approx 1GB of memory, while at the same time being unnaceptably slow.
The worst part is that it is getting worst, not better.
The status is "working on it", but would you mind to give us insights on what are you doing to address it and estimation on when do you expect to have this issue fixed?
The "workaround" provided is not acceptable. You might as well ask the users to not use Teams at all. Teams meetings are very interactive, and I usually use my Surface Book 2 monitor as well as 2 external QHD monitors while having meetings, in order to view participants on screen 1, share screen 2 and take notes on screen 3. As others have already written: this is not acceptable - it is a Microsoft program, on Microsoft OS running on Microsoft Hardware - you are it. You acknowledged the problem August 14th 2020, that is 7 (SEVEN) months ago. What are you doing to solve this???
MS Please fix excessive memory usage by MS Teams. Problem is >3 years old.
Ohh, wait, that's not in the roadmap:

The "workaround" is nothing but putting a low speed spare tire on your car - an emergency solution - not a fix. We are using this everyday, often with additional screens when running meetings etc. - because they are needed - stripping away anything that makes a smooth teams meeting seems like the wrong way to "solve" a problem ?? I have dusted of a 10 year old mac book pro - that runs teams, multiple screens with zero problems. I am a big fan of the Surface - but this is not acceptable - it is a Microsoft program, on Microsoft OS running on Microsoft Hardware - you are it...
Does Microsoft intend on fixing this issue anytime this century? I'm a math teacher who bought a Surface Pro because I thought it would be absolutely sensational to teach my students with. We're now going on just about a year of online teaching because of the pandemic, and Microsoft hasn't solved the issue since I first discovered it over one year ago. The lag when I screen share renders my Surface Pro utterly unusable. Honestly, how does this not embarrass the company more? I'm considering selling my Surface, which has become and unusable piece of garbage for the purpose I purchased it for, and replacing it with a simple iPad. Let me be clear: I've never liked Apple products, but at least those work as intended.
useless on my brand new surface pro 7 too. I wish I'd gone for the M1 MacBook Air. This ought to be more embarrassing for Microsoft but clearly it isn't.
Same issue here on my surface pro. Please fix it ASAP as it is so frustrating and counterproductive. It is fascinating that an MS software perform much worse on an MS PC. I mean, do you pretest how your own products work and interact with each other? I don't expect much synergy but at least please don't be so destructive.
I’m using a Thinkpad, brand new, and I experience the same thing. Teams takes over the computer and making it unusable. Everything lags. I thought it was the computer, but reading through this thread makes it look like Teams might be to blame. I have similar experiences with Zoom and Slack as well when sharing the screen, but Teams is much worse than the others.
I definitely don't think it's just related to team. With a Surface Pro 7 (and previously a 4 and a 5) all the remote sharing tools I tried have the same issue and make the machine almost unusable because of its slowness. It's a real pain and a real reason to chose another machine.
Thank to MS to fix it ASAP !
15" Surface Book 2 i7 w/ GTX 1060. Running Windows 10 1909 (latest my org supports). I've had the computer rebuilt (reimaged) twice to no avail. I've updated to the latest Surface Book 2 drivers, and have flashed the Surface Dock firmware to the latest rev multiple times over the last two years. My home ISP is fiber and delivers 100 Mbps down and 10 Mbps up, and I connect via WiFi. At my organization i have gigabit ethernet.
Regardless of whether I'm using the built-in screen of the Surface, or while connected to my external monitor, Teams performance is intolerable. The integrated GPU (not the discrete GTX 1060) will become nearly entirely consumed. My Teams video lags and my computer, in general, becomes unresponsive. Changing between windows while this is occurring is dreadfully slow, and forget about sharing my screen, that's a no-go. My colleagues use the background blurring effect, but whenever I try to use it things go south quickly. Recently I found that fitting attendees videos to frame, as opposed to letting Teams actively crop them, helped ever so slightly. But even so, general performance during Teams videos is horrible.
I'm the only one on my team with a Microsoft Surface. I'm also the only one on my team experiencing this issue with Teams. The rest of my organization primarilly uses Dell Latitude and Optiplex comptuers. They do not have these problems.
As an aside, I have similar performance issues when using Zoom, while my colleagues do not. I have my suspicions that the Surface Book 2 simply has a toxic brew of tech that is causing my video conference related issues. I manage IT at my organization, and I will not be getting another Surface, nor will I recommend them. It's astonishing to me that MS would not be able to remedy these issues for the two years I've had the device, and given the current pandemic-driven remote work world we're living in this is more important than ever.

any update regarding high CPU when using Teams?. we are facing this on lenovo thinkpad
Bhavin Gangar commented
it seems so counterintuitive that other company devices work fine with teams and Surface struggles .. but that is exactly what i have been experiencing .. extremely unresponsive UI when the video calls are on
Teams is so laggy to the point it almost doesn't function as a messaging app on a late 2015 iMac 4770k, 32GB ram, NVME SSD. This should be #1 priority.
This seems to be a well documented issue caused by CPU usage spikes. Typing lags constantly in teams, perhaps once every 5 to 10 seconds, regardless of background CPU usage. I'll be typing a message and hit enter to post it, and start typing another one only to find the start of my next sentence has been included in the first message because Teams has lagged. I've checked activity monitor and can see noticeable spikes caused by the 'Microsoft Teams Helper' process.
Vote here for the same issue - here we have more chance:
