moving emails from a folder to another folder has become very slow (pop, win10)

I have a very large profile (9GB) with several email accounts, one having several hundred folders. Lately, moving emails from one folder to another has slowed down very much. Task Manager shows 90 - 100% disk when moving emails.

Moving email on the local disk, or using IMAP and so every move has a load of overhead in messaging back and forth with the server?

These email accounts are not IMAP, they are POP.

To clarify, all emails that are moving are on the local disk, some folders are larger than 2GB.
