Whole-stack analysis and optimization of commercial workloads on Server systems

The evolution of the Web as an enabling tool for e-business introduces a challenge to understanding the execution behavior of large-scale middleware systems, such as J2EE [2], and their commercial workloads. This paper presents a brief description of the whole-stack analysis and optimization system - being developed at IBM Research - for commercial workloads on Websphere Application Server (WAS) [5] - IBM's implementation of J2EE - running on IBM's pSeries [4] and zSeries[3] server systems.
