I'll do some more tracing and see if I can see mutt working hard in

so that the waiting for character read() doesn't see any delay I might
be able to see where the time goes.

Matthias suggested this:

   strace -o tr -tt  mutt ....

If you want less log to deal with you can strace a process from outside:

   strace -o tr -tt -p pid-of-mutt

That would let you fire it up just before the action (change mailbox) which you know contains the delay. Might get you a better targeted log.
