PM for Azure DevOps here. We've been investing heavily in our user experience and our CI/CD experience, so I'm sad to see that we've disappointed here.

Some of these complaints I would agree with - in particularly, we're not (yet) caching build resources - though we're working on this now. But most of these complaints I was quite surprised to hear; not an experience I would want someone to have or what I see from the majority of our customers. So this is certainly a place where I'll follow up with the author to learn more.

So sure, I'm missing caching that I've had on Travis. But honestly, it builds reliably fast anyway. On Travis, I always needed to wait a LONG time to get macOS agents, on Appveyor, we were limited to 2 parallel builds. Here, everything starts all at once, completes under 10 minutes (there's quite a lot to build and test).

If I could, I would love to have an sccache ( https://github.com/mozilla/sccache ) compatible distributed free caching solution for my C++ projects. That'd be a killer feature!
