Starting with an empty config except for a header cache dir setting, I notices a distinct slowdown of the scan at about 80%. Odd. So I moved the cache sideways and let it rebuild:

This brought a nice linear scan.

Yeah, the header caches can get inefficient after a while. I'm glad that helped.

So I started adding back in my config files (I source a few). Here's the glaring one:

   source ~/rc/mutt/aliases-auto

8407 aliases, nearly 2MB in size :-)

Really, it is a bit excessive. Particularly since I think I don't ever use aliases anyway.

Yes, Mutt's internal structures used for aliases are not designed for that many. It could lead to quite a slowdown in some circumstances. Do you have $reverse_alias set in your config?
