I am using the clipper on a dataset that contains many simple polygon features and few very large and complex features. I run the clipper in parallel processing and it seems to work correctly. However, the groups that contains the complex features take hours to complete while other groups with simple feature take few minutes. In this case there is no real performance gain with the parallel processing.
Do you have tips to speed up the whole process? Is it possible to divide the complex features in smaller part ?
