I had a similar problem for a year. Every time I created an empty folder in the Finder, I would have to wait 5-7 seconds before it would appear so I could rename it. And every time I deleted something, I would have to wait before it would disappear. This was the solution that worked for me -- increasing the Double-Click Speed in the Accessibility preferences!! https://forums.macrumors.com/threads/finder-is-slow-laggy.1848574/page-2#post-24521915
