Well, isn't, as with rsync, the travel time through the filesystem (to find out
what's to be sync'ed) incompressible, in which case it would take more than a
few seconds on a large mailbox (I'm testing but in more complex conditions) ?

Is dsync, for that matter, fastest than rsync (maybe because using
dovecot-uidlist or similar) ?

Besides, how about client side indexing while in this incoherent, not yet fully
sync'ed state ? Wouldn't there be corruption risk ?

Thanks.
