[proxmox.com, config.pm] Subject: [pmg-devel] [PATCH pmg-api] 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 11:57:33 -0000 One pmg-smtp-filter process uses at least 220 MiB. When having 100000 rules one process can take up to 330 MiB. Therefore using 300 for the calculation more closely reflects the current memory usage of one filter process.
