This project is one of the Google Summer of Code 2007 projects for MySQL.
I am a graduate student of University of Toronto, and my mentor of this project is Paul McCullagh.
The goal of this project to provide a performance analysis tool for a MySQL storage engine PrimeBase XT. We aim to help developers to locate the bottleneck of the system. In contrast to traditional profiling tools, we focus on how to capture the impact of the resource contention through measuring the time spent on waiting critical resources, such as I/O, memory and locks. We also try to provide context information to help developers to identify the critical path.
