MYSQLTuner

MySQLTuner  is a perl script for mysql optimization.

To get uset it:



  wget http://mysqltuner.com/mysqltuner.pl
  chmod +x mysqltuner.pl
  ./mysqltuner.pl

I acheived amazing performance boost (server load dropped form 10 to 1) following the suggestions of this script, i.e.:



General recommendations:
    Add skip-innodb to MySQL configuration to disable InnoDB
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    query_cache_size (> 64M)
    table_cache (> 64)







Thanks mediakey.dk for introducing this amazing script.
