[Geocoding] Maximum realistic performance (geocoded addresses per second)

[Mathias Versichele]

I see. Judging by the graphs, the server handles around 1000 successful
results per minute or almost 17 per second. Which is lower than what I am
seeing right now. Does that mean that I shouldn't expect any more gains? I
understand the different factors influencing performance, but I'm more
trying to get a grasp of the maximum I should be aiming at (on a dedicated
system).
