Using flame graphs when profiling Java applications
Flame graphs are a great way to get an overview of the entire call tree and to visualize performance characteristics. This screen cast shows how the jclasslib bytecode viewer is profiled. A class file is opened and the parsing of the class file is analyzed with the flame graph.
