It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., This was a chance to talk about other things I've been working on, such as the present and future of hardware performance.

I've also used and helped develop many other technologies for debugging, primarily perf, Ftrace, eBPF (bcc and bpftrace), PMCs, MSRs, Intel vTune, and of course, [flame graphs] and [heat maps]. I hope my last two books, [Systems Performance 2nd Ed] and [BPF Performance Tools] serve Netflix well in my absence and everyone else who reads them.

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.

It's an important vendor-neutral space to share the latest in technology. USENIX has been a great help to my career and my employers, and I hope it is just as helpful for you. And now, helping bring USENIX conferences to Australia by giving the first keynote: I could not have scripted or expected it.

Back in 2015 we'd have BPF (iovisor) meetups in Santa Clara and most contributors would be there in person, with some having travelled. While tech workers are well suited for remote work (savvy with communications technologies) there are benefits with office work, and I don't think remote work is for everyone. Making it Work.
