views and they seem to function OK.
Views are matched one by one, you can have a look at function
get_matching_view() in file bin/named/server.c.
Having said that, the matching can be fast enough or not depending on
the configuration. Typically it's better to do a test in lab than theorize.

What sort of QPS are each of your servers handling?

I believe that some newer versions of BIND can share zone information
across multiple views. Check out the "in-view" statement that goes
in a
zone {...} clause.
