Hotsos Symposium 2011 Speaker Spotlight - Gerwin Hendriksen

There's still time to sign up for Hotsos Symposium 2011. We'll take your registration right up until Monday morning! Go here to register!

Presentation Title: GAPP Improvements: a Method to Diagnose and Predict Performance in Complex Architectures

Presentation Abstract: This session demonstrates how to use "General Approach Performance Profiling" (GAPP) to profile end-user response times and predict performance in multi-tier architectures, regardless of complexity. This session focuses on recent improvements to the GAPP method that was introduced in 2008.

Business processes are influenced by many components like Web Servers, Portal Servers, Oracle Internet Directory Servers, Database Servers, Application Servers, etc. The power of GAPP is its ability to help you manage environments of arbitrary complexity, regardless of which technologies you've implemented.

The presentation will show results from actual customer experiences in SOA-based systems with more than three nodes. A live demo will show how easy it is to use GAPP to predict performance behaviors on a system using a load generator to create different scenarios.
