Continuous Profiling for Scale

Go offers pprof, a powerful tool to profile the performance of a program. But the collected data is often limited if you don’t profile on your production environments, as you have to artificially simulate workloads that may be different from production workloads. With continuous profiling, you can sample real-world performance in production with minimal overhead. This talk covers how an intern at Google evaluated and implemented open source tools to implement continuous profiling, leading to more efficient Go code.
