GAPP performance approach

Yesterday evening I visited an Amis query about performance. Speaker this time was Gerwin Hendriksem from Amis, a real performance freak. He designed his own approach for solving performance problems, and it was a good session. Gerwin used Oracle data mining to spot performance issues. He gathered system data for more then a year and using data mining to analyze and predict the bottlenecks. He succesfully used this approach with at least two customers.
Next week he will be giving the same presentation in the VS at the Hotsos symposium in Dallas. He also gave his approach a name, the GAPP approach.
So, be ware of te GAPP....
