"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. -Peter
