I'm not aware of any systematic benchmarking. You can have a look at the
server stats for nominatim.osm.org at 
http://munin.osm.org/openstreetmap/pummelzacken.openstreetmap/index.html#nominatim
to get an idea how that server is doing.

Note that query speed can be vastly different depending on the hardware you
have, what kind of area is imported and what kind of queries you have (even
what kind of format your search term has can make a huge difference). So I'm
not even sure benchmarks could have more than anecdotic value.
