I developed the original JVM changes to allow [mixed-mode flame graphs], I pioneered using [eBPF for observability] and helped develop the [front-ends and tools], and I worked with Amazon to get [PMCs enabled] and developed tools to use them. I could help not only Netflix but all customers of the cloud. Thank you.

There's an arms race to add eBPF (BPF) to commercial observability products, and in this post I'll describe how to quickly do that. People like to show me their BPF observability products after they have prototyped or built them, but I often wish I had given them advice before they started. You might not even like BPF.

" I pictured how this is used to walk stack traces in my BPF book. Stack Frame with Base Pointer ( x86-64 ABI ) Figure 2-6: Frame Pointer-based Stack Walking ( BPF book ) This stack-walking technique is commonly used by external profilers and debuggers, including Linux perf and eBPF, and ultimately visualized by flame graphs.

At USENIX SREcon22 APAC I gave the opening keynote on the future of computer performance, rounding up the latest developments and making predictions of where I see things heading. This talk originated from my updates to [Systems Performance 2nd Edition], and this was the first time I've given this talk in person!
