I guess m question is quite general and doesn't target only the MySQL:

How is MySQL performance meausred?
What metrices are used to determine the efficiency of a database structure?
Are there any tools out there that measure database performance?

Thank you.

So many possible answers... ultimately, it's a combination of query performance and optimal resource utilization. There are many such metrics too (buffer hits, cache sizes, queries/sec, open tables, locks, etc.), all of which need to be examined as a whole. To be sure, there a few that are dead giveaways, but it's rarely that simple. I ran across a tool call "mysqlreport" a while back which does a pretty good job of giving you a handle on things.

Feel free to ask anything more specific, and maybe I can be more helpful.
Seriously... if people don't start reading this before posting, I'm going to consider not answering at all.
