TITLE:
What Will My Performance Be? (A Resource Advisor for DBMSs)

ABSTRACT:
Administration tasks increasingly dominate the total cost of ownership of database management systems. A key task, and a very difficult one for an administrator, is to justify upgrades of system resources (CPU, memory and storage) with quantitative predictions of the expected improvement in workload performance. We describe the design, implementation, and evaluation of a Resource Advisor, a tool that provides such predictions in response to "what-if" questions about hypothetical resource upgrades. It is based on end-to-end monitoring of transactions in a live system, followed by simulation and analysis to predict workload performance after a hypothetical resource change.

BIO:
Since November 2002, Dushyanth Narayanan has been a researcher at Microsoft's Research Centre in Cambridge, UK, where he thinks about performance modeling, power management, and other research areas beginning with the letter "p." In August 2002, he acquired his Ph.D. from Carnegie Mellon University, where he worked on adaptation in interactive wearable applications.
