It is good practice in MySQL to check, optimize and repair all databases regularly.

Most software packages will automatically check and optimize database tables on your server per website but this is not always the case so it may need to be done manually. Some databases or database tables could also become corrupt due to service bottlenecks or other failures and a repair should do the trick.

All of this can be done with the mysqlcheck command if you are the server or database administrator.
