Bonjour,
Sous Kubuntu 20.04 64bit
Version d'Ancestris : 12.0.11644
Java : 17.0.2+8-Ubuntu-120.04 - /usr/lib/jvm/java-17-openjdk-amd64

Mémoire allouée 4Go
Process 3652 - java
Summary
The process java (with pid 3652) is using approximately 1.1 GB of memory.
It is using 1.1 GB privately, and a further 12.8 MB that is, or could be, shared with other programs.
Dividing up the shared memory between all the processes sharing that memory we get a reduced shared memory usage of 590.0 KB. Adding that to the private usage, we get the above mentioned total memory footprint of 1.1 GB.
Library Usage
The memory usage of a process is found by adding up the memory usage of each of its libraries, plus the process's own heap, stack and any other mappings, plus the stack of its 41 threads.
