Microsoft in November offered some snapshots of performance improvements compared to June 2020 when the app became essential for meetings due to the coronavirus pandemic.
Compared to June 2020, switching between chats is 32% faster, while switching between channels is 39% faster. The June 2022 release delivered 20% faster switching between chat threads, and 28% switching between channel threads. These performance improvements were linked to the framework upgrade.
As noted by The Verge, former head of Microsoft Teams engineering Rish Tandon in 2021 explained the new architecture would help it add support for "multiple accounts, work life scenarios, release predictability, and scale up for the client". Microsoft is also adopting Apollo GraphQL and contributing to the GraphQL project .
The company's plan is to release a preview of the new Teams app in late March. Users will be able to toggle back to the existing app.
