Apologies for the Microsoft source on this, but it was all I could find. Interestingly, in December, Raygun posted about comparing performance of different nodejs frameworks[1]. In that, though they conclude it's not the fastest, they say: > We still utilize express in our ingestion layer though in the future we may switch to an different language entirely. So I'm guessing this is where they went. It would be great to see what other considerations they had switching away from nodejs, and what else was considered.
