Will anyone from the Teams product group offer an update on performance of the windows app? It seems like the majority of comments today are around CPU usage, memory usage, latency for chat history, etc, but nobody seems to be willing to offer a meaningful comment around it. For two years, all we've heard is that the group is looking into improving performance. Does that mean a new app is coming out soon NOT built on the 'super efficient' Electron rails?

ChrisWebbTech it still regularly uses 1.5GB RAM and over 30% CPU during meetings, slowing our 8th Gen Intel i5 CPU 8GB RAM HP EliteDesk G4 Mini PCs to a crawl when users have so much as 5 Chrome tabs, the Outlook 365 Desktop app, the OneNote UWP App, and the Microsoft To-Do app open. Normally I would agree that memory usage != performance issues, however, when your machines have to split available RAM between the integrated graphics and other mandatory company programs, it's hardly acceptable to see Teams using 20% of the total available, especially when other apps built on the same ElectronJS platform (Discord & Slack, for example) manage to consume almost nothing during a call or when switching text channels. When I use MS Teams to join meetings from my home computer with a 4th Gen i7 and 24GB RAM, it still chugs while utilizing the same resources, albeit a tad less CPU. To be clear, my home PC is able to switch to other applications a little faster, but the extra RAM and processing power don't seem to help Teams performance at all, indicating a problem with the code that makes up Teams' core.I understand development takes time, but it's going on 6+ years now with Teams still exhibiting performance issues. Maybe it's time for a rewrite of Teams from the ground up similarly to Slack's recent rewrite?https://microsoftteams.uservoice.com/forums/555103-public/suggestions/17219609-teams-uses-600mb-and-is-super-slowhttps://www.infoq.com/news/2019/07/slack-desktop-successful-rewrite/https://slack.engineering/rebuilding-slack-on-the-desktop-308d6fe94ae4 Tagging jcgonzalezmartin and jimharpert so they can see Teams using more than 1GB RAM at least once in their life. Also looping in VasilMichev and Eric DeVaudreuil because they're spot on with their prior comments about high resource usage. Also making StevenC365 aware of why one might not want to see a single application utilize such high amounts of resources.

Sure, try telling this to anyone running Teams on a laptop/netbook with 4GB RAM 🙂

ChrisWebbTech Yet the minimum requirements still say 2GB! That's unrealistic. In an organization that wants to move to Teams that has spinning disks, and 4GB of RAM in desktops, it's a product that is impossible to support. It's frustrating to see the team continuing to post on things like integrations with third parties, when the core of the product is still extremely inefficient, and there doesn't look to be any priority put towards it.

It's a lost cause mate, that's how "modern" development works.

Well, many of us still struggling with this. ChrisWebbTech Following my experience during Teams implementation on Citrix (with resource offloading) Teams reducing 30-40% of the server density, comparing with Skype For Business. I have also learned, that Teams using a lot of cache file mechanisms in order to reduce ram footprint, so does not really help for SSD wearing, and just simply kills an HDD based machine. But still knowing the development challenges that confirmed on various channels, the app is still sluggish in 2020/05, (and was the same problem in 2018, when we started to use Teams... )I do not think corporate Office or blue-collar users must use at least 8th+ generation Corei5 machines and AMD Ryzen 5 (Zen+) or better CPUs, in order to use the solution quite smoothly. If I use my workstation (HP Zbook G6 with 6cores, 12threads), I feel a significant performance drop, when we turn on a camera or use only for audio meetings. A HyperV machine not doing that drop! I can also admit, that was some improvement from 2018, but just some. I personally think: Instead of focusing on funny features, like shiny background on-camera meetings, will be better to optimize the app core I think.

Can't believe how bad it is. I have a relatively new 6-core XPS, and Teams can bring it to a hault! Using up 50% of my CPU for absolutely no reason, and it just continues to run until I kill it. I had to switch to the web version, lol. How do you build a desktop version that performs worse than the web app?! Wow.

If there are no plans to move away from electron then the uservoice ticket should be closed as "working as intended" so people don't hold out hope for improvements. If you aren't intending to fix performance then maybe focus on adding/improving teams functionality available via API so 3rd party clients can take over some of this performance work.

Dustin_Halvorson there are no plans that I've heard of for any new app not built on Electron. There have been significant enhancements to Teams that make it faster for things like starting chats, navigating etc. There are still a few areas of this to come e.g. faster tenant switching.

Fundamentally Teams client will continue to operate like a browser, with a memory footprint like a browser.

Teams has been improving over time. If you compare Teams client today, vs. Teams client last year, there is a massive difference in performance. There def. is more work that could be done, but I have definitely noticed changes being introduced over time.

  I agree, Teams is using less resources now than a year ago. But there is still room for improvements.
  
  Dustin_Halvorson I guess you have seen the uservoice about this and Microsoft answered there that they have improved performance for the Teams client and they are still working on improvements.

    Is it though...
    
    That's just the client sitting idly in the tray, within our company tenant with just 10 teams or so I've joined...

I guess we will have some updates around Ignite, but for now not specific news on Teams Client performance
