Ideas on how to best set up annual large Matrix-like operation?

Here’s what I want to do and maybe you guys can guide me as to the best way of doing it. Once a year I need to do two different 1200x1200 distance matrix calculations (drive-time). The locations come from all across the entire state of Texas, so a large OSM download is needed.

I’m on Windows and I’m having a difficult time even getting graphhopper set up on a such a big OSM file - run out of memory.

Any help you can offer is greatly appreciated.

You can raise the usable memory e.g. via export JAVA_HOME="-Xmx4g -Xms4g"

Thanks, that worked.

Separate question - I’m running it via Docker. How do I make a simple change, like tweaking highway speeds with my docker setup?
