If the size is stored in maildir filename (,S=123) this is pretty fast, otherwise it's pretty slow because Dovecot stat()s the files, but afterwards it stores them to dovecot-uidlist file. So the main difference is that Maildir++ requires rescanning the quota periodically, while dict quota never rescans unless you run doveadm quota rescan.

But dict quota, for enforce limits, can only be used with dovect as LDA? 
I'm using Maildir++ with qmail/vpopmail for local delivery and dovecot 
cannot enforce limits on delivery. With this configuration the only way 
to update dictionary is "doveadm -A quota rescan".

Is correct?
