I think it would be great if the performance of ArcGIS Desktop 10.x could be matched, at even 50%. Much of the great ideas and efficiency concepts built into the new software are zeroed out by basic performance problems. For example, it just took 2 minutes to cut a 5 acre polygon in half. The spinning blue wheel is our best friend here in our company. It gives us lots of time during the day to refill coffee, go for a walk, etc.
All sarcasm aside, it's a major problem. We have teams of IT staff testing and monitoring users and traffic to troubleshoot these issues for dozens, if not hundreds, of users across our company. It appears we do not have enough degrees and people available to get ArcGIS Pro to work satisfactorily. It shouldn't be this difficult and it didn't use to be.
Software licensing costs with ESRI continue to skyrocket while software performance tanks.
