It did after a while.

I've enabled vm-external-
still takes ages. Would it be worthwhile to look at how other MUAs do it
and try to optimize the code that handles IMAP folders? For comparison,
mutt loads my Debian.debian-devel folder in 3 seconds and records
changes almost instantly. Even after enabling
vm-enable-
folder using 100% CPU on one of my cores. Loading a folder with 21290
messages took at least 35 minutes (my X session crashed thereabouts),
and emacs cycled between "Debian.
NNNN", then sorting the messages, then recreating the summary, at least
twice.
Moreover, stuffing / saving the folder Debian.debian-devel (keybinding
'S') after I marked roughly 20 messages as read took over 14 minutes
(from 14:44:22 until 14:58:34).
Might it be worthwhile retitling this bug to "vm unusably slow on large
IMAP folders"? I unfortunately don't yet know any emacs lisp, but am
willing to help out where I can in debugging this issue.
For reference, you can find my .vm file on github[0].
Best wishes,
Ryan
