rblsmtpd isn't any more (or less) efficient at checking DNS RBLs than spamdyke but there are several reasons not to use both. First, in terms of efficiency, spamdyke will check other (faster) filters before it performs the DNS RBL checks. If the connection is going to be rejected for some other reason (e.g. missing rDNS), spamdyke will skip the DNS RBL checks entirely. This can save some processing time on your server (which can be significant for high-traffic servers). Second and more importantly, rblsmtpd doesn't understand SMTP AUTH -- it will reject any connection, whether it is authenticated or not. spamdyke allows authenticated connections to bypass all of its filters.
