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.

As software performance degrades or fails, the chaos engineers’ findings enable developers to add resiliency into the code, so the application remains intact in an emergency. Chaos engineering matured at organizations such as Netflix, and gave rise to technologies such as Gremlin (2016) , becoming more targeted and knowledge-based.

One question I’ve seen posed a few times in the past several months is whether performance really is a moral or ethical concern, or if that’s all heavy-handed exaggeration. When you stop to consider all the implications of poor performance, it’s hard not to come to the conclusion that poor performance is an ethical issue.

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!

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance.

TL;DR: performance budgets are an essential but under-appreciated part of product success and team health. We constrain ourselves to a real-world baseline device + network configuration to measure progress. Performance budgets are set early in the life of the project. Budgets are scaled to a benchmark network & device.

I recently was asked the following question by an online retailer: “Why should I invest in monitoring the user experience when I already have monitoring for our database, infrastructure, app server, and network?”. Instead of asking that question, I asked them this: “Are you a network or hosting provider?

I wrote a page on it: [perf]. - **eBPF**: tracing features completed in 2016, this provides efficient programmatic tracing to existing kernel frameworks. The hardest part on Linux is now done: kernel support. It's the official profiler.

In recent years the trend has been to increase core-level performance by the use of SIMD vector instructions, and to increase package-level performance by the addition of more and more cores. The core does not have enough load bandwidth to perform all of these extra load operations at full speed.
