Performance Tuning

If you assume that nothing mid-process is being out put to temp, then all the data has to be held in memory.

You can reduce the memory that a process requires by reducing the number of features, reducing the number of attributes, removing geometry. Or you can redesign the process so that the memory-intensive data never hits a blocking transformer.

Also, if your memory usage in the windows Resource Monitor looks like this, in my experience FME.exe will only use the 'free' memory, not the 'available' memory.

I have had to export each Feature into two separate Features, to stop the FME Heatmap from crashing..

I have about 15 FME models to run, is it possible to run them sequentially, not concurrently...

To stop it crashing??

Yes, definitely do that.

Other than that, if you can tell us a bit more about what you are trying to do exactly and how much data you are processing we should be able to give you more detailed advice.

Greetings,

In ArcGIS Pro I can use the he Kernel Density tool to create Heatmaps.

I cannot do this in FME using the Heatmap Transformer, it keeps crashing.

Is there an alternative Transformer??

I select the input Feature (Point)

This creates a Heatmap.

I have 1,626 Point records (Centroids) that I need to create Heatmaps, using values in a field.

The values range from 50 to 82, shown below.

Any suggestions what is the best Transformer to use to output high quality Heatmaps??

If FME Transformers are not suitable, could I run gdal in FME??
