Why I setup my server to boot on power. So I want to boot and run as quickly as possible to minimize downtime due to reboots or power-outages. It happens more than I’d like. Goal Document performance settings for Ubuntu 22.04 Settings Not a performance setting, but ups the map count limit to allow for Docker to be able to run ELK. Set vm.max_map_count to no less than 262144 (one time configuration) 1 2 # Run once, loses setting after reboot.
