high-performance MySQL tuning script

High-performance MySQL tuning script written in perl that will provide you with a snapshot of a MySQL server?s health. Based on the statistics gathered, specific recommendations will be provided that will increase a MySQL server's efficiency and performance. The script gives you automated MySQL tuning that is on the level of what you would receive from a MySQL DBA.


   * Memory Usage: Calculates MySQL memory usage at max load and makes
     recommendations for increasing or decreasing the MySQL memory
     footprint. Per-thread and server-wide buffer data is calculated
     separately for an accurate snapshot of the server?s configuration.
   * Slow Queries: Reviews the amount of slow queries relative to the
     total queries. Slow query time limits are also analyzed and
     recommendations are made.
   * Connections: Current and historical connection counts are
   * Key Buffer: Takes configuration data and compares it to the actual
     indexes found in MyISAM tables. Key cache hit rates are calculated
     and variable adjustments are suggested.
   * Query Cache: Query cache hit rates and usage percentages are used
     to make recommendations for the query cache configuration
   * Sorting & Joins: Per-thread buffers that affect sorts and joins
     are reviewed along with the statistics from the queries run
     against the server.
   * Temporary Tables: Variable recommendations are made to reduce
     temporary tables that are written to the disk.
   * Table Cache: Compares total tables opened to the currently open
     tables. Calculates the table cache hit rate in order to make
   * Open Files: Determines if the server will approach or run into the
     open file limit set by the operating system or the MySQL server
   * Table Locks: Finds table locking that forces queries to wait and
     makes suggestions for reducing locks that require a wait.
   * Thread Cache: Calculates how many times MySQL must create a new
     thread to respond to a query.
   * Aborted Connections: Finds applications that are not closing
     connections to MySQL properly.
   * Read/Write Ratios: Calculates the percentage of read and write
     operations on your MySQL installation.
