My talk for BayLISA, Oct 2013, launching the Systems Performance book. Operating system performance analysis and tuning leads to a better end-user experience and lower costs, especially for cloud computing environments that pay by the operating system instance. This book covers concepts, strategy, tools and tuning for Unix operating systems, with a focus on Linux- and Solaris-based systems. The book covers the latest tools and techniques, including static and dynamic tracing, to get the most out of your systems.
