Tested with - linestrings, count 153742, total count of vertises 1 million, processing rate 7300 vertises/second - polygons, count 362, total count of vertises 2 million, processing rate 9500 vertises/second
Computer is a 2.8 GHz single core Pentium from year 2004. Java memory consumption does not raise during the process at all. I consider this script is effective enough for any production. -Jukka- Rahkonen Jukka wrote: > > Hi, > > The tool does the job fast and obviously correctly.
