I am sure that you know Mysql quite well: this advanced, very used open source database is one of the key softwares behind the LAMP stack (Linux, Apache, MySQL, PHP). Sun (now Oracle) estimate that about 50% of all deployed databases are mysql installations.
Very often, these installations are kept at default settings – and for good reason: generally, default parameters are configured for safety and, if you don't really know what you are doing, you can severely impair your server reliability and/or performance. Moreover, many mysql installations deal with basic, simple tasks, where performance is not a crucial factor.
However, there are cases where you really need to speed up your mysql deployment: for example, think to a frequently visited web site with mysql backend, or an application that executes a lot of queries/transactions. In this case, what you can do to extract more speed from your beloved mysql server? This article will shed some light on this topic.
