Overall the RPZ zones have little impact on traffic.

I captured three hours of traffic across three of our most popular DNS
hosts for a total of 755,938 queries. Of those queries only 1403 queries
generated an RPZ hit -- for a ratio of 0.18%.

The most effective RPZ zone was the rpz.spamhaus.org zone; accounting
for 61.9% of the RPZ hits; rpz.surbl.org accounted for the remaining hits.

This is in an ISP environment.
