I'd be curious to get some feedback on my header caching patch for maildir folders (can be found at http://www.sigpipe.org:8080/mutt/). Initial reports are that it greatly speeds things up since after the first time you load a mailbox, you only have to traverse the list of files in a directory without actually opening them up for reading. I'm not familiar with the structure of inodes and how fast it is to traverse the list of files in a directory, but I suspect it will be significantly faster than the current method.
