I'm using FME Desktop (2022.1.3.0) to run an AreaonAreaOverlayer on two very large Geopackage files. It's been running for 4 days and currently on "Preparing spatial indices for intersection phase# 2... 11.91% done". My PC has 128Gb of RAM and 40% of that is free, yet FME is only using 7Gb and thrashing my pagefile.sys.

Does anyone know how I can force FME to use more physical RAM please?

Thanks

Rob
