Hi,
I’ve upgraded my laptop to Qubes 4.3 a some time ago, and I’ve noticed that the disposable qubes are preloaded after every suspend/resume cycle. So right now I have ~10 disposable qubes running, but I certainly don’t need that many. Each disposable qube is getting ~3GB of RAM, which seems a bit high.
I ended up disabling preloading of disaposablw qubes in global config, and this behavior went away.
