I've been using Visual Studio 2010, and then 2017 and 2019, with a pretty big solution loaded, and never ran into issues like you mentioned. For me it was always pretty snappy, including refactoring actions. OTOH I've hardly ever used or installed Resharper (or Rider). When I did try Resharper, I found Visual Studio was dog slow, very much like what you described, and it provided me with very little benefit compared to what I already had in VS.
