Yep agreed, this would be my top speed killer investigations:

- check with a fresh profile (or even rename the folder beneath it, so
you get the 'hey upgrading from 2.x ?' message
- really stop Windows virusscanners (that is: as admin also stop all
scanner related services, and not that they are not 'autostarted'
again...).
- have a look at your Windows network drives (I know some years ago
there were issues with getting big files from network drives on Windows)
- thin client issues: sometimes thin clients are really too thin for
serious work, but I've also encountered issues on more hefty clients
- browser issues? I sometimes see the 'scanning' of folders containing a
lot of geodata in QGIS browser panel is taking some cpu resources.

Can you try to start QGIS with the following options:

qgis --noversioncheck --noplugins --hide-browser

(with me this takes 2 sec to start)

My gut feeling is that python is slow in certain Windows environments.

Last: see if on another pc you have the same issues, if possible?

PS Happy Debian Linux user here, so all knowledge is from working at
clients machines, my virtual Windows machine on my laptop (even that one
is fast enough) or old posts.
