LDA Indexing
============


Dovecot v1.0's deliver updates the main index file while message is being saved. This is useful with >>mbox<< format, especially if 'mbox_very_dirty_syncs=no'. With >>Maildir<< the benefits of this are pretty small. 
Dovecot v1.1's deliver updates also cache file, which can be very useful with all mailbox formats. It means that when client wants to fetch the message's metadata (e.g. some header fields) they're already found from the cache file and Dovecot doesn't have to open and parse the message file. This reduces the needed disk I/O and CPU usage. 
See >>IndexFiles<< for more information about what the index files contain.
