You consume some CPU and burn some disk I/O ops. Daemons that use the
indexed file with re-start at a convenient point in time (i.e. not in
the middle of a transaction, ...). Regardless of size, you should not
be re-building indexed files frequently (more than a few times a day) ,
if you are, use *SQL or LDAP.
