Notes:
  • The performance depends very much on the data to be processed. For the topology functions the  quality of the input data is a major factor - the more unresolved intersections (polylines) or overlaps (polygons), the slower the process.
  • The number of vertices in the input dataset has also major influence on the performance. See the test results for the Polyline To Point and Point To Polyline functions above.
  • The tests above are performed on the same PC and the same data with both versions of ET GeoWizards
  • All the tests are performed on Intel(R) Core(TM)2 Duo 2.66Ghz, 2 GB of RAM
