A nice way to play with these GC and DGC settings is monitoring JVM heap via jvisualvm and Terracotta shared heap via terracotta’s Developer Console.
Thanks for all the excellent tips.
At 8GB it crashed with 3G + 0.5G + 0.5G as the total used kept increasing to 8G, so I increased the RAM to 12G to see what would happen and found it does plateau at around 10G. This got me thinking about what is using up all the extra RAM, and what needs to be done if I want to increase RAM allocated to Servoy64.
I’ll change one thing at a time and give it a reasonable window so we can see what makes the most difference.
Ah ok. You can also try other JVM versions to see if the non-heap memory usage is the same.
