The index rebuilding itself doesn't take hardly any time at all. Also if
old indexes exist, they aren't rebuilt but rather just updated.

The biggest potential performance hit with losing indexes is losing
cache file. Clients which often request the same information from
mailbox (eg. mail headers) are faster if the information is already
available from Dovecot's cache file so it doesn't have to open each mail
separately. Webmails especially do that.
