Processors average 90% idle, peaks are low, iowait is low, the system is
not swapping, response time is good, and our users are happy all around
the country. What is crazy about that?

I don't know how the rest of the world does it, but we have been doing
it like this since 2006 and it has worked great and we have never
regretted having multiple instances of mysql. In fact, it is really
great because we can maintain each customer's service individually, stop
and start mysql without affecting other customers, turn query logs on
and off for each customer, customize performance parameters, and so on.
I can maintain a customer's database right in the middle of a production
day and the other customers won't even notice! It has been great being
able to do all these things.

Then you're just not Googling very well. :-)
