Solved…??
Generally Setup only shows up (on my system) as an active task when it’s checking for updates. Sometimes this can take quite a while, even though I’m on DSL, because due to heavy internet traffic (most often) or whatever other reason, Setup is taking longer than usual to work its way through the database of available servers. Once it’s found one it can properly connect with, the download/update is quite quick.
So while your situation may be different from mine, in my case noticeable delays are while checking for available servers to (1) check for new updates, and (2) download and install anything new found. I’m not sure whether this sequence needs to check for a server both times, which would lengthen the delay, or whether it can all be done with the first successful connection (perhaps someone more knowledgeable could enlighten me, please and thanks?).
