My current project is around 7 years. I have tried to limit the number of CIs, but should probably have done more to limit them further.
I have never heard of a hard limit but, with the recent limitation for budget moves to 250 items, I somehow feel InEight never intended we should have too many CIs.
I have around 4500 items with 3500 terminals, and I'm struggling with performance.
What is your experience with number of CIs?
