What mailbox format do you use? This shouldn't be a problem with for example mdbox, probably not with sdbox either and with mbox/maildir there are settings that can improve this.
This is mbox.
Or are you not talking about opening the mailbox, but about clients redownloading all the mails all the time?
I don't think the client downloads the whole mailbox each time. It takes so long on a 1 GB mbox that the users would have complained. However, I can see a lot of disk I/O activity for pop daemon operating on the bigger mbox (easy to spot looking at the process uid)
Try mbox_very_dirty_syncs=yes
