Microsoft Teams: new app is 2x faster and uses 50% less memory

Microsoft released a public preview of the new Microsoft Teams app for Windows today. The new application is a complete rewrite of Microsoft Teams and Microsoft claims that it is up to 2x faster than the old and uses up to 50% less memory and 70% storage when compared to the old application.

The old Microsoft Teams application was built on Electron, a massive framework that gives apps a lot of capabilities, including cross-platform support. It comes at a cost, as Electron is not exactly resource-friendly.

Microsoft explains that it moved from Electron to WebView2, from Angular to React, and to using Fluent UE collection in the new Teams application.

An article on Microsoft's Tech Community website offers details on the move: "Key decisions made included participating and standardizing on the Fluent UI collection of UX controls, transitioning from Angular to React for building user interfaces, moving data processing out of the main thread to a client data layer worker, and lastly, transitioning from Electron to leverage WebView2 as the host."

Microsoft Teams preview design-elements

There, Microsoft explains some of the development goals of the transition, which include performance optimizations, security hardening, an improved video pipeline and other goals.

Microsoft ran several benchmarks and claims the following performance stats of the new Teams application when compared to the old:

  • The application launches up to 2X faster
  • The joining of meetings is up to 2X faster
  • Switching channels and chats is up to 1.7X faster
  • It consumes up to 50% less memory
  • It consumes up to 70% less disk space

Microsoft published a video on the official Microsoft 365 website and on YouTube. The video on the Teams website shows how the old and new Teams application do in regards to performance. The video on YouTube is by Jeff Teper, President of Collaborative Apps & Platforms, and it provides more details on the new Microsoft Teams application.

The new Microsoft Teams is "faster, simpler, more flexible, and smarter", according to Microsoft.

Simpler refers to design adjustments that Microsoft made to various areas of Teams, including notifications, search, message management and channel organization. The blog post Designing the new era of Teams offers a deep dive into the design changes that went into the new Microsoft Teams application.

The old Microsoft Teams application has a rating of 2.7 out of 5 on the Microsoft Store. If the new Microsoft Teams proves to be that much better, its rating is likely improving in the future.

How to get the preview of Microsoft Teams

The preview release of the new Microsoft Teams is available for Windows only at the time. Microsoft promises that it will release the new application for Mac later this year.

The option to try the new Teams app should be displayed as a "Try the new Teams" toggle, according to Microsoft. Teams users may use it to switch between the classic and new version of Teams. Teams users who do not see the toggle should try signing out and in again, or contacting their IT administrator for guidance.

Additional information on the new Teams is available here. There, Microsoft highlights some of the features that it is still working on, including support for government clouds, advanced calling and meeting features and more.

  • Mac, VDI, EDU, and web platforms
  • Government clouds (GCC, GCC-High, DoD)
  • Advanced calling features, such as call queues and reverse number lookup
  • Advanced meeting features, such as breakout rooms and 7×7 video
  • Teams and channel creation, cross-posting, and channel announcements
  • Search in chats and channels
  • Files app, 3rd party apps, and Line of Business (LOB) apps

Microsoft plans to roll out the stable version of the new Teams later in 2023.

    Are these articles AI generated?

    Now the duplicates are more obvious.

    1. boris said on March 19, 2023 at 11:48 pm

      This is below AI generated crap. It is copy of Microsoft Help website article without any relevant supporting text. Anyway you can find this information on many pages.

  2. Paul(us) said on March 20, 2023 at 1:32 am

    Yes, but why post the exact same article under a different title twice on the same day (19 march 2023), by two different writers?
    1.) Excel Keyboard Shortcuts by Trevor Monteiro.
    2.) 70+ Excel Keyboard Shortcuts for Windows by Priyanka Monteiro

    Why oh why?

    1. Clairvaux said on September 6, 2023 at 11:30 am

      Yeah. Tell me more about “Priyanka Monteiro”. I’m dying to know. Indian-Portuguese bot ?

    Probably they will announce that the taskbar will be placed at top, right or left, at your will.

    Special event by they is a special crap for us.

    If it’s Microsoft, don’t buy it.
    Better brands at better prices elsewhere.

    All new articles have zero count comments. :S

  6. Anonymous said on September 5, 2023 at 7:48 am

    WTF? So, If I add one photo to 5 albums, will it count 5x on my storage?
    It does not make any sense… on google photos, we can add photo to multiple albums, and it does not generate any additional space usage

    I have O365 until end of this year, mostly for onedrive and probably will jump into google one

  7. St Albans Digital Printing Inc said on September 5, 2023 at 11:53 am

    Photo storage must be kept free because customers chose gadgets just for photos and photos only.

    What a nonsense. Does it mean that albums are de facto folders with copies of our pictures?

    1. GG said on September 6, 2023 at 8:24 am

      Sounds exactly like the poor coding Microsoft is known for in non-critical areas i.e. non Windows Core/Office Core.

      I imagine a manager gave an employee the task to create the album feature with hardly any time so they just copied the folder feature with some cosmetic changes.

      And now that they discovered what poor management results in do they go back and do the album feature properly?

      Nope, just charge the customer twice.

      Sounds like a go-getter that needs to be promoted for increasing sales and managing underlings “efficiently”, said the next layer of middle management.

    When will those comments get fixed? Was every editor here replaced by AI and no one even works on this site?

    Instead of a software company, Microsoft is now a fraud company.

  11. ard said on September 7, 2023 at 4:59 pm

    For me this is proof that Microsoft has a back-door option into all accounts in their cloud.
    quote “…… as the MSA key allowed the hacker group access to virtually any cloud account at Microsoft…..”

    so this MSA key which is available to MS officers can give access to all accounts in MS cloud.This is the backdoor that MS has into the cloud accounts. Lucky I never got any relevant files of mine in their (MS) cloud.

  12. Andy Prough said on September 7, 2023 at 6:52 pm

    >”Now You: what is your theory?”

    That someone handed an employee a briefcase full of cash and the employee allowed them access to all their accounts and systems.

    Anything that requires 5-10 different coincidences to happen is highly unlikely. Occam’s razor.

  13. TelV said on September 8, 2023 at 12:04 pm

    Good reason to never login to your precious machine with a Microsoft a/c a.k.a. as the cloud.

    The GAFAM are always very careless about our software automatically sending to them telemetry and crash dumps in our backs. It’s a reminder not to send them anything when it’s possible to opt out, and not to opt in, considering what they may contain. And there is irony in this carelessness biting them back, even if in that case they show that they are much more cautious when it’s their own data that is at stake.
