I don't quite recall. IIRC it was an hour maybe, so it wasn't like the builds were extremely slow, but it means people didn't want to run the tests locally, so if you're trying to get your work committed and then there's some failure CI picked up that you didn't each iteration can be an hour, and that made people feel unproductive and slow because some of them struggled with context switching back and forth and even the ones who could do it didn't like it. Which I totally agree with, context switching and small delays can be painful to feeling productive. Obviously full test coverage is a very good thing to have. But, people hate waiting. They ended up having a proliferation of smaller repos and replacing it with manual rec/sync work which was IMO not a good idea, but probably felt more like "work" rather than waiting.
