I think you need to supply a bit more details.

Sorry for unclear requirement the geometry I am processing is Line geometry calculation angle for segment and doing matching between them. this is the only data processing facing "Creating spatial index" issue.

2_1_Simple Geo Matching v8-mar.log.txt

here is the log file

But, I don't see the 2 hrs in the logging?

This is the example ….

@nielsgerrits Do you have any idea how to solveit ?

I can't reproduce your problem so not sure where to look for a solution. Also because the log is different from the problem one.

For example, in the log, line 1081 "Automatic_UTM_Zone_Converter_Sorter(SortFactory): Sorted 2964 feature(s)" takes up more than 40% of the processtime. GeometryReplacer takes 19%. Further dissolver (12%) and Neighbourfinder (15%) will take more time when the dataset gets bigger.

I would try to make sure it is caused by writing the features, because I doubt this is the issue. First disable the writer, if the problem goes away, try a another location (local vs network), if this doesn't solve anything try another writer, etc.

If it is really down to the writer you might need to create a support case. But I am afraid Safe will need to be able to reproduce the problem as well to help you.
