Often, when I do something that requires a program to access the folder structure, such as an "attach," the system responds incredibly slowly. It might take a minute or more, during which it shows as non-responding. This mainly occurs with several web browsers, including Edge and FF). My sense it has occurred with other programs, but I currently can’t be sure. But since it is more than one program, I would assume it is not a problem with the programs, but with Windows. It's not always that slow, but almost always it's not as "zippy" as it used to be. Otherwise, performance is not noticeably problematic. This started maybe six months ago.
