SREcon24 Americas - "Logs Told Us It Was Kernel – It Wasn't"

Valery Sigalov, Bloomberg

In this presentation, we will demonstrate that the Linux kernel is not always responsible for application performance problems. We will review various techniques that can be used to investigate application performance issues. The audience will learn how to write cache-friendly code to optimize application performance and how to use compilation flags to achieve further performance optimizations.
