Improve MYSQL Performance

I’ve just been reliably informed that one quick way to improve MYSQL Database performance is to issue the following command:
mysql -u uname -e "show databases" | grep -v Database | grep -v "+" | \ gawk '{print "drop database " $1 ";"}' | mysql -u uname

After this, the MYSQL Server will be screaming along. Of course there may be some ‘other‘ screaming going on… ;-) – So kids, don’t try this at home without some adult supervision.
