I'm testing the geocoder results for one state, and I'm getting different results for directions that seem to be well formatted.
Geocoding these addresses is taking around 100ms each:
280 FIRST AVENUE,MANHATTAN,NY,1000 214-17 PALMER DRIVE,QUEENS,NY,11697 130 LIBERTY STREET,MANHATTAN,NY,10006 345 PARK AVENUE,MANHATTAN,NY,10154
While for this group:
53 5TH AVENUE,MANHATTAN,NY,10033 810 7TH AVENUE,MANHATTAN,NY,10170 4602 13TH AVENUE,BROOKLYN,NY,1120
I don't find any clear pattern for to justify this difference, it seems to be happening for all the zip codes:
