Teams Performance
Also surprised this isn't mentioned more. I guess just most people aren't using Teams. Regularly causing issues this way too. 30% CPU and 1.5GB RAM used (commonly makes Outlook also use 30% CPU too)
4 way video meetings expect 100% CPU and 2GB RAM. Running on:
Intel Core i5-8365U
8GB DDR4 RAM
Plenty businesses still on 4GB RAM so ... 
Learnasyougo one of my IT clients is looking to switch their entire office from a mix-mash of subscription services over to an all-in-one Office / File Collaboration suite, so this is just another consideration I have to take into account despite them running 4th gen i5 Dell business all-in-ones with 8GB RAM and a barebones Windows installation.
The heavy resource usage by the Outlook desktop application will definitely be a deciding factor as we evaluate spending $12 CAD per seat on licensing. (In case anyone at Microsoft is motivated by more revenue, that'll be around $1000 CAD per year for this particular office - not a lot compared to large organizations, but still a chunk of money none-the-less.)
- We use Teams and Outlook latest versions on 8GB ram machines with no issues. There must be something there causing the issues somewhere in the chain.
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.
we are having the same issues, but running a mix of different surface pro's included the latest 7th gen.
The irony is, we are due to be pitching to Microsoft corporate for some consultancy work next week using Teams, and we know the presentation will be awful because of their own software/hardware issues.
On my clients machines we run nothing other than a fresh install of Windows 10 Pro (installed directly from Microsoft's own Media Creation Tool), Google Chrome, Office 365 Business, and Windows Defender. On my day-job's work PC's we run the same specs, although have newer 8th gen i5 processors, and Teams still chugs along sluggishly when in meetings or switching between channels.
Don't get me wrong; I'm enjoying the integration with Office 365 apps that Teams brings to my workday, as it allows for improved collaboration, however...
"if I'm constantly battling the sluggishness of Teams' user interface, am I really more efficient than if I were simply not using Teams?"
Discord, Slack, WebEx, Zoom, GoTo Assist, TeamViewer, or even Microsoft's own Skype all utilize less than 5-10% CPU and never go above 300-500MB memory at most during meetings, so that kind of narrows things down to the problem being Teams itself.As I said before: maybe it's time to rewrite Teams from scratch like Slack did last summer, or at the very least, conduct an in-depth user-study to understand why it eats resources on certain systems.
