Go Performance Tales

Jason Moiron, a Datadog software engineer, shares his experience with optimizing the performance of a new service written in Go. He learned that using integer map keys can significantly improve performance, and that AES-NI processor extensions can boost string hash performance. Additionally, he discovered the importance of reducing locking and unlocking in channel communication, which improved throughput by nearly 6x. The author also explored the use of Cgo for optimizing compression, but found that it had some overhead due to coordination with the Go scheduler and memory management. Ultimately, Moiron emphasizes the importance of measuring everything and using the tools available in Go to get the most performance out of the language.
