I don’t know, maybe it’s my beefy PC, but I’ve never had any performance issues with Teams.
We’re in the surface ecosystem where I work and the performance is abysmal. Granted we’re at 8gb ram on our standard models so not much to go off but it’s a super heavy application for what it’s doing
My fridge has 16gb
And I have 8gb in my work laptop. C’est la vie
