There is caching with the internal completion, just not between emacs
sessions. So the second and following completions in a given session
should be much faster. I have almost twice that number of messages, and
the lag is barely noticable here. So maybe something's wrong if you're not
restarting emacs and still noticing completion lag.  You might have a
look at the variable "notmuch-address-completions". For me this has a
bout 3700 entries in it at a steady state.

I think the plan was/is make this search customizable in various ways,
but so far nobody got around to it.
