Great performance and user experience remain a topmost priority for us. Application launch time has seen improvements in the recent build. We will continue making improvements across the product including channel to chat switching and overall resource consumption.

AdminAlex (Teams Engineering, Microsoft Teams) responded · Jul 3, 2019

Performance has been and continues to be a big focus area for Teams. One main area we have made improvements in is responsiveness for the most frequent user actions of switching between Chat, Channel, and Activity. We are also focused on reducing resource consumption and application load time. More improvements are on the way.

The feature is still being worked upon. Many different changes are going into Teams and will provide a slow but steady pace to our performance increases.

I don’t have any new details at the moment but hope to get some additional feedback in the next several weeks.

The survey has now been completed.

Thanks to everyone who took time out to complete the survey. Your continued feedback really helps us target the issues.

I’ve moved the status back to working on it. The team is digging through all the great feedback and taking further steps to improve your experience.

Thanks again for your feedback and support!

Warren responded · Jul 23, 2018

A number changes have gone out and the feature team would like to hear your feedback again about performance.
This is a quick survey that will help target the future updates.

Please take a couple minutes to take this survey. (It should only take about 2 minutes to complete.)

I want to assure you that overall performance, speed, cpu, memory, etc. are all being worked upon.

We want to get these improvements to you ASAP – and so are releasing fixes as they are made, which in turn will snowball into a larger improved feel. (As opposed to holding these in earlier rings, and then doing a big bang update.)

Please know that the feature team is hard at work on dozens of items to make these improvements. We’re seeing great gains in performance in earlier rings of deployment, and you will soon see these improvements as they’re released to further rings.

Again, it won’t be a single update that’ll address all the concerns, and it will take time. But gains are steadily and surely coming.

This item is actively being worked upon.

There are several dozen separate update pieces being worked upon that will provide an overall performance boost. As these updates get closer to completion I’ll provide a timeline as they prepare to roll out.

There is a lot of good progress, as I get more details I will share them. The survey was a huge help in pin pointing how we can best serve you with these updates.

Thank you!

We are working to improve the performance and looking at the issue across many of the features and best ways to make a positive impact.
This is getting a lot of focus and though I don’t have any timeline to share, it is getting a lot of traction and investigation.

As timelines and further details are provided I will share that information with you as soon as I am able.

Thanks,
Warren

First off, thank you for all the feedback you have provided.
I have some good news to share! We have made a big improvement in how Teams uses memory. A large impact came from how Teams uses the Giphy picker.
The best news though… is that our memory usage improvements are out now! Heavy users should be seeing a significant (approx 230mb) decrease in memory usage.

Thank you all for your input and please keep it coming. Your feedback helps us build a better product.

Hi everyone — just a heads up that I edited the description to include some of the most poignant comments from this thread. If you have any other info you can share about performance and speed, please keep adding them to the thread here. I’ll routing each to the Perf team, since that really helps for emphasizing urgency, demand, and user pain.

THANK YOU for helping us make Teams better!

Sincerely,
Suphatra

Hi everyone, I sent over your feedback to the performance team and they let me know they are actively working on this.

“Our development organization is continually working to improve product performance and has several efforts currently underway around memory usage, action responsiveness and application start time. Updates which improve performance are part of our regular update process. Thank you for your feedback regarding the performance of Microsoft Teams.”

I will check in on them in a few weeks to see if we can get exact numbers/details on what’s been improved, and I’ll let you know.

Meanwhile, have a great weekend and don’t forget to set your clocks forward by an hour for Daylight Savings!

Sincerely,
Suphatra

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

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
