    Am running the Parallels 17 trial version on a Macbook Pro 16 inch 32GB RAM;
    As below, see that:
    a) actual RAM usage of Windows 11 is 16-17 GB;
    b) the Hardware settings of Windows 11 are set to Automatic - 4CPU's and 8GB RAM;
    c) the Optimisiation setting is set to "No Limits";

    Not sure how to interpret the settings and understand how they interact with each other to result in the Usage. Can anyone clarify?

    Sorry, should have stated. Am on Monterey 12.0.1.

    Well that's super interesting... It's exactly as you say (via the KB article). So I guess it hasn't been fixed yet. (command/results below)

    for pid in $(ps ax | grep prl_vm_app | grep -v grep | awk '{ print $1 }'); do sudo footprint -p $pid; done
