WOSP is a forum for researchers interested in the intersection of Software Engineering and Performance Evaluation. Software Performance Engineering (SPE) research aims to build predictable performance into software by specifying and analysing quantitative behaviour from the early development phases of a system throughout its entire life cycle. Analysis may be based on various kinds of modelling, design and measurement tools. Modern software systems are complex (distributed over a wide area, mobile, running on heterogeneous platforms, belonging to different administrative domains) and often have strict performance and scalability requirements. This workshop brings together software engineers, developers, performance analysts and modellers who address the challenges of increasing system complexity, rapidly evolving software technologies, short time to market, incomplete documentation, and less than adequate quantitative models and tools. We expect a strong mixture of academic and industrial participation.

The previous WOSP events were held in Santa Fe, NM (1998), Ottawa, Canada (2000), Rome, Italy (2002) and San Francisco, CA (2004). Building on their success, this workshop provides a forum for the growing community of SPE researchers and practitioners interested in quantitative analysis of software systems, at any stage of software development.

Topics of interest include but are not limited to the areas listed below. The emphasis is on software system performance, especially from the middleware up to the application level:
• SPE Process and Practices:
    • Defining and managing performance goals and requirements
    • Performance budgeting for development groups
    • System and software architecture assessment
    • Performance-oriented design/implementation
    • Performance annotation of software specifications
    • Experience with SPE
• Modelling Tools and Techniques:
    • Performance evaluation methods-tools-frameworks
    • Gathering and exploiting data
    • Automated model building from software specifications
    • Capturing user behaviour and QoS requirements in software performance models
    • Model and data interchange formats
    • SPE in the context of OMG's Model Driven Architecture (MDA)
    • Methods and tools to guarantee Quality of Service of adaptive/intelligent software applications
• Performance Measurement, Modelling, and Management for Software Systems:
    • Performance testing methods and tools
    • Measurement and monitoring techniques and services
    • Analysis of measured data
    • Quality of Service of applications
    • Autonomic systems
    • Performance modelling of software applications
    • Performance modelling of software architectures
    • Performance modelling of software analysis and design models.
    • Performance modelling and evaluation of software components within Intelligent Systems: performance ontologies, performance-oriented knowledge representation, natural interaction software.
    • Middleware performance
    • Component-based system performance
