Increasing the available Java memory

To make KaDeck use all the available memory (min. 8GB recommended), you need to configure the JVM.

To increase the memory available to the Java process, use the typical parameters -Xmx for the maximum and -Xms for the initial memory. To pass these parameters to KaDeck, you can set the environment variable "KA_DECK_OPTS".

For example, as an argument for the Docker image:

-e KA_DECK_OPTS="-Xms8g -Xmx12g"
