Python geoprocessing performance

[ab1]

Hi,

I have a python geoprocessing that takes a lot of time. The geoprocessing calculates geometries using points, polygons, buffers, and cursors.
Do you have any hint of how to optimize the geoprocessing?
Would it be shorter in time if I used the Java API?

Thanks.

Some things to think about...

• If you are at 10.1 or later, use arcpy.da - it's a lot faster


• Use the shortcuts (SHAPE@, etc) to access the geometry -- this is much faster than accessing the shape field directly.


• Remember you can use geoprocessing tools directly on arcpy geometry objects (this may help you design a zippier workflow)
