Useful measurement

Chris Beal
Senior Principal Software Engineer

One of the talks I went to at Oracle Open World was one on measuring performance of your application on an Oracle database. The talk was by Cary Millsap of Method R titled  "Instrumentation: Why You Should Care"

It was interesting in many ways, topics such as writing debug data to a ring bugger of shared memory reminded me of how we used to work before dtrace came a long.

There was  one fantastic quote from Mr Millsap, which I think is worth repeating

 "If obviously different experiences yield the same measurement, then clearly you're measuring the wrong thing"

 Sage words indeed
