I am considering an upgrade to dovecot which uses maildir instead of mbox, will roundcube still function?

I've been using dovecot with maildir together with roundcube for over half a year.

In fact, roundcube only connects to dovecot via IMAP. Wether behind the IMAP there is mbox or maildir doesn't even matter much.

So which of the two performs better under load?

on many levels MailDir is more efficient and performs better, it does have some down sides but when compared to the performance and latency load generated when connecting to mbox, MailDir still excels, its better to have the MailDir hosted on a separate raid array preferably raid1 or raid10 for optimal performance.

MTA that use mbox or mbox go thru more processes when handling the mails, if a user has a mailbox with 100mb of data (mail), the mbox would always have to handle the single file storage in indexing, deleting, writing etc while as Maildir reads/writes directly to the designated filesystem directory saving resources and operates more flexibelly and efficiently. maildir with optimal filesystem and disk array would outbeat mbox anyday anytime on modern or older hardware.
