One interesting thing to note is that there are lots of internal tools (CLI, web UI, etc.) that are REALLY slow. Things that are heavily used in the fast-path for development (e.g. code search, code review, test results) are generally pretty quick, but if there's a random system that has a UI, it's probably going to be very slow - because there's no budget for speeding them up, and the only people it annoys are engineers from other teams.
