Subject: [pve-devel] [PATCH ksm-control-daemon] ksmtuned: use PSS instead of RSZ for caluculating memory usage
Date: Mon, 8 Apr 2024 15:25:53 +0200 [thread overview]
Message-ID: <20240408132552.293049-2-s.lendl@proxmox.com> (raw)
PSS properly accounts for memory usage of shared libraries and is
therefore better suited when summing up memory usage of multiple
processes.
