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.)

Thank you again for all your feedback and response.

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!

Thank you all for the amazing response to the survey! The response was huge and very, very helpful.

The survey is now closed. We will start digging through all the provided data and continue working to improve Teams.

I will continue to post updates as we progress, so stay tuned.

Thank you!

We need your feedback!

Performance of Teams is a concern and we need some additional information to help drive this work to resolution.

Please take a moment to fill out this online survey. It only takes a couple minutes!

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 think CPU load annoys me even more than memory usage.

Sorry, but I have to pile-on. Teams is great, but Teams is also a beast of an app and a resource hog. Would be nice if it was snappier using it. We have 9th and 10th Gen Core i5 processors with 16GB RAM and Teams still is a little sluggish at times.

Teams need's to utilize less memory. It is debilitating when trying to work on other applications or share applications via teams meeting. This negates a large portion of the usefulness of Teams. My creative team can't participate in meetings without closing out of all Adobe applications, and my account team can't collaborate via teams in PowerPoint or Excel without it crashing.

906MB for me which means my Surface is sitting at 80% Memory, I can barely do anything else with this type of usage!

Teams uses 800 MB out of 2gb Ram and I am not even doing anything, can you please find a way that It will not use roughly 40% of what I have available?

It looks like it takes 40% of what everyone has and uses it, that is not acceptable for an app that I don't use but need to have active on the background

Just by opening Teams - it takes around 300 mb without doing anything. Still in top 3 by just opening Teams
And if you use it for online meeting , it jump in the top of using resources.

Teams definitely hits PC performance. I'm using an i7 based PC with 8G RAM and it is just about possible to do other things as well as run Teams.

Looking forward to celebrating the one year anniversary of Alex's empty promises! Performance is shockingly poor on Mac and Teams is one of MS's flagship products. Please please get competent leadership in to prioritise basics over flashy gimmicks.

I can only agree. MS teams is taking a lot of my memory, making pc slow.
Is always in Top3, and mostly at the 1th. place.... NOT good
Normal it's 300+400 MB when I'm not using teams, and if using we go to 400-500MB or even more

Four years after the initial request and no large reduction in Teams memory usage.

When is the replacement product for Teams going to be released?

Teams has been out over 5 years and very old.

Teams definitely impacts PC performance in an extreme way. and needs to be addressed. Advising users to close other open apps, turn off virtual backgrounds, etc. as a workaround does not address the full issues and actually diminishes the use of modern features users like.

Teams remains a performance hog, bottom-line. Memory utilization may have a improved slightly, but CPU use is still off the charts.

Today seems to be one of the better days, Teams is "only" using 1.3GB of RAM.

Microsoft, you should be utterly ashamed of yourselves for pushing out this diabolical piece of badly written, unreliable and resource hogging crud. It's truly awful. PLEASE can you fix this?! It's been FOUR YEARS for heavens sake!

Dear @Admin, it's been almost a year since the last update from you and covid-19 has made us even more dependent on Teams. Can we please deprioritise functions like "together mode" and instead focus on this performance issue? Thanks.

Always hogs my memory, today 786MB, 10% of available RAM. Not acceptable for professional use.

Why even when I clear everything, restart fresh, etc. Teams is still using anywhere between 800 and 1GB of ram???? How is this acceptable in such a prolific application? Don't you guys have any standards over there??? How can you ship an application which for many users will consume 1/8th or more of their available RAM.

This is still terrible. My company gave me an Intel i3 machine and when I'm in a Teams meeting, CPU usage is constantly 100% and it becomes borderline unusable.
