When having a few 1000 states to perform on each client, the lag for initiating the next state centrally from the server was quite noticeable - in the end a single run took more than half an hour without any changes (for a single host!).
After that we re-evaluated with salt stack being the outcome scaling well enough for our O(2500) clients. Note, I ave not tracked if and how ansible progressed over the past ~2yrs which may or may not exhibit the same problems today.
