This course provides the system administrator with methodologies and tools to evaluate system performance and recommend solutions. Students will learn to use Performance Co-Pilot™ and accounting to identify applications that may have performance problems. Students will then profile these applications to evaluate common code problems such as cache thrashing or false cache sharing.
