Tuning of any database is required in order to optimize its performance. A well-tuned database performs faster and maximizes the use of system resources. If your database is not optimized, it will response poorly and eventually effect your business. Similarly if you are using MySQL for storing your data then don't forget to optimize it. MySQL provides different storage engines and each storage engine has unique design and properties. So it is important to optimize each storage engine according to its design. I will discuss performance tuning tips for InnoDB.
