-`wof-libpostal-crawl` traverses a directory containin GeoJSON files and queries an instance of `wof-libpostal-server` with an address string derived from one or more properties in the GeoJSON feature. For example, this:
-
-```
-./bin/wof-libpostal-crawl -libpostal-host localhost -processes 200 /usr/local/data/whosonfirst-data-venue-au/data/
-parsed 697614 files in /usr/local/data/whosonfirst-data-venue-au/data/ in 314.434 seconds avg ttq: 836 ms
-```
-
-Produces a file that looks like this:
-
-```
-id,address,results

-## Performance and load testing
-
-This assumes the server a pair of single-CPU m3.medium instances, fronted by a load-balancer, and a URLs file containing 1517965 addresses in California. There is also a URLs file with 18M addresses from most of SimpleGeo but that is 8GB and I got bored waiting for [siege](https://www.joedog.org/siege-home/) to it to load it in to memory...
