Elastic's release of version 8.12 introduces Performance Presets for Elastic Agent and Beats, aimed at simplifying performance tuning and enhancing default settings to boost efficiency. The new defaults improve throughput by up to 50%, reduce memory usage by 10%, and significantly decrease concurrent connections and disk I/O for Elasticsearch. Four main presets are offered: Balanced, which is now the default, Optimized for Throughput, Optimized for Scale, and Optimized for Latency, each catering to specific performance needs such as higher data ingestion rates, scalability for large deployments, or reduced latency for real-time analytics. Additionally, a Custom option allows for granular control over performance settings. These changes are only applicable to Agents on version 8.12 and later, with older versions maintaining their existing configurations.
