Mysql enterprise edition vs community edition

InnoDB has several internal performance enhancements, including reducing contention by splitting the kernel mutex, moving flushing operations from the main thread to a separate thread, enabling multiple purge threads, and reducing contention for the buffer pool on large-memory systems.ДЈ. Advanced users can fine-tune their I/O responsiveness through several configuration options.Дў. The new algorithm and default configuration values are expected to improve performance and concurrency for most users. Improvements to the algorithms for adaptive flushing make I/O operations more efficient and consistent under a variety of workloads. The changes also provide more control over configuration of the I/O subsystem. Changes to the InnoDB I/O subsystem enable more effective use of available I/O capacity. MySQL Enterprise Thread Pool, As of MySQL 5.5.16, MySQL Enterprise Edition distributions include a thread pool plugin that provides an alternative thread-handling model designed to reduce overhead and improve performance.Дў. Faster recovery from a failed or aborted ALTER TABLE.ДЈ. New compact storage format which can save up to 20% of the disk space required in previous MySQL/InnoDB versions.Дў. You can find below some of the performance improvements applied to InnoDB these last years (non exhaustive list): MySQL 5.0ДЎ. Indeed number of improvements as been done to innodb storage engine in the last MySQL versions.

This blog aims to make a performance comparison between the different MySQL versions/editions and also comparing the differents MySQL forks such as Percona Server and MariaDB.
