That is a ridiculously low performance, especially on a Desktop. You should expect rates in the millions per hour for a single locator. Make sure your reference data is correct and 'perfect'. That is no null or blank values, unique keys and all required fields populated. On ArcServer the peformance will be much slower because you need to send the addresses across a network, process and return the results. In that case performance for bulk geocoding will probably be too slow to be useful. So stick to a network based geocoder for bulk geocoding.

You also might try getting the GeoEvent Service configuration to a working state on your Win7 machine, then exporting the GeoEvent Processor's configuration from the Site > GeoEvent Processor > Configuration Store page, and importing the XML into a clean instance on your Win2008 R2 machine. An easy way to clear out the configured elements (Inputs, Outputs, GeoEvent Definitions, etc.) is to stop the Windows service running GeoEvent Processor, locate and delete the files from the C:\ProgramData\Esri\GeoEventProcessor folder. I would recommend leaving the ...\certs folder so that you don't have to re-import the SSL certificate as trusted. Also, if you are running 10.2.0, be sure to leave the ...\connectors folder (this will be rebuilt for you if you're running 10.2.1). If you find that a more aggressive cleaning is needed, you can locate and delete the C:\Program Files\ArcGIS\Server\GeoEventProcessor\data folder to remove any cached elements; the folder will be rebuilt when you restart the Windows service. As long as both machines are running the same version of GeoEvent Processor, you should be able to share configurations this way so that you don't have to reconfigure Inputs, Outputs, GeoEvent Definitions, and GeoEvent Services. There's a lot of touch points you have to make sure you've replicated on each box ... and forgetting something simple like a GeoEvent Definition or tagging a TRACK_ID onto a event definition field can easily make it look like one server is working and the other isn't. - RJ
