Most of my mailboxes are delivered via procmail.  The *huge* mailboxes, I 
use dovecot LDA; as well as a small number of Sieve users are using it.
the LDA does caching of headers at delivery time, which is why I use it on 
huge mailboxes (100,000 messages in the mailbox).  Small mailboxes, I 
don't see so much benefit to using deliver (ie, <10,000 messages).

That's my experience, at least, on a high volume but small number of users 
mail system.
