Try yourself with imaptest (http://imapwiki.org/ImapTest):

imaptest - select=0 clients=<try different values>

It'll authenticate the same user, but as long as you don't enable auth
cache it'll still do the LDAP lookups and you can get a pretty good idea
of the performance.

My guess is that the performance bottleneck won't be authentication
binds, as long as the latency between Dovecot and LDAP server is small.
