The maildir format doesn't specify any sort of indexing.  However, a number of 
maildir-enabled MUAs do their own indexing.  For instance, KMail creates an 
index for for all of its mailboxes, including maildir ones.

In my experience, very very large mailboxes using maildir tend to be quite a 
bit slower than mbox to load up the first time but are noticably faster 
loading every time after that (assuming an indexing mua).
