Blazing Performance with Flame Graphs

"How did we ever analyze performance before Flame Graphs?" This new visualization invented by Brendan can help you quickly understand application and kernel performance, especially CPU usage, where stacks (call graphs) can be sampled and then visualized as an interactive flame graph. Flame Graphs are now used for a growing variety of targets: for applications and kernels on Linux, SmartOS, Mac OS X, and Windows; for languages including C, C++, node.js, ruby, and Lua; and in WebKit Web Inspector. This talk will explain them and provide use cases and new visualizations for other event types, including I/O, memory usage, and latency.

Brendan Gregg is the lead performance engineer at Joyent, where he analyzes performance and scalability at any level of the software stack. He is the author of Systems Performance (Prentice Hall, 2013), and primary author of DTrace (Prentice Hall). He was previously a kernel engineer at Sun Microsystems where he developed the ZFS L2ARC, and has also developed numerous performance analysis tools. His recent work includes performance visualizations.
