I've been working on migrating our workflows from ArcMap to ArcGIS Pro over the last year, and one consistent annoyance is the performance of the join tools in Pro. Joining csv files, tables, and feature classes to each other in ArcMap has always been a cinch and usually takes no more than 10 seconds. In Pro however, both the join and remove join(s) tools run multiple times slower than in ArcMap and often freeze the software as well.
I've experienced these issue from Pro 1.4 through 2.2.3 without seeing any improvement. In what is supposed to be newer software with improved performance, I don't understand why this straight-forward and essential task is such a hindrance.
