Explore micro-optimization techniques for Go code in this conference talk from GopherCon 2018. Learn how to improve performance by writing more efficient Go, starting with a hash function implementation. Follow along as the speaker optimizes code from a direct RFC implementation to surpassing the standard library's performance. Discover the impact of API design on performance, avoid microbenchmarking pitfalls, and gain an introduction to profiling. Acquire practical tips for optimization, including algorithmic improvements, program tuning, and diving deep into performance analysis. Examine additional examples from standard libraries, particularly in cryptography, and other high-performance Go projects to further enhance your optimization skills.
