[proxmox.com, config.pm] Subject: [pmg-devel] [PATCH pmg-api v2] config: adjust max_filters calculation to reflect current memory usage X-BeenThere: pmg-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Mail Gateway development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 10 Jan 2024 14:05:15 -0000 One pmg-smtp-filter process uses at least 220 MiB. By adding more entries into filter objects the memory usage increases and therefore 230 seems like a good value that reflects the current memory usage of one filter process.
