The article outlines practical guidance to optimize the performance of a MISP instance, especially when managing large volumes of data and many users. Key hardware recommendations include using fast NVMe storage for high IOPS, allocating around half to three-quarters of system RAM to the InnoDB buffer pool, and choosing modern MySQL/MariaDB versions. On the software side, tuning PHP settings (e.g., memory limits, execution times, session handling via Redis) and adjusting database handlers (e.g., MysqlExtended or MysqlObserverExtended) are highlighted as ways to improve responsiveness.

Fine-tuning of MISP settings is also covered: reducing correlation loads via MISP.showCorrelationsOnIndex, limiting REST search results, and applying synchronization filters to restrict data ingest. The documentation emphasizes indexing of key tables (attributes, events, objects) using included shell scripts, and using tools such as the built-in benchmarking interface to profile endpoint execution time, SQL query time and memory usage. These optimizations help administrators maintain smooth operation even for high-traffic, high-scale threat-intelligence environments.
