Explore the intricacies of Nashorn performance in this 49-minute Java conference talk. Delve into strategies for achieving native-like performance with dynamic languages on the JVM, including optimistic types, static compiler enhancements, and field representation. Learn about property maps, types, and optimistic builtins, as well as techniques for relinking callsites and implementing partial evaluation. Discover JVM and JDK optimizations, lazy compilation methods, and the use of profiling tools like Java Flight Recorder. Gain insights into the future of Nashorn performance optimization and its potential impact on Java development.
