"forwarding" will give you only a small fraction of a resolver's capability,
most prominently its cache.  While that may be a good way of running in
production (as long as the forwarder's availability is sufficient),
what you test appears to be the performance of the system you forward the
queries to.  To get a clearer picture of unbound's performance, you
could test it in its full resolver mode: use no forwarder at all and
let unbound do the whole work of iteratively finding and compiling
responses to incoming queries. Unless, of course, something in your
operations environment doesn't let you do this, but then it might not
serve too well as a performance test setup.
