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"
