Dive into a comprehensive conference talk on Go performance optimization and memory management. Explore the need for a new runtime scheduler, comparing Go's approach to Java. Understand the Go runtime scheduler, Communicating Sequential Processes (CSP), and the Go memory model. Learn how to write, run, and interpret benchmarks, including using benchstat for result comparison. Delve into profiling techniques and analyze performance differences. Gain insights on compiler optimizations and best practices for Go performance. Conclude with valuable study references to further enhance your understanding of Go performance optimization.
