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!

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.

My talks on Failing Over Without Falling Over are still very relevant, but AWS did finally release a key new service that implements key parts of the architecture: AWS Route 53 Application Recovery Controller. For example AWS launched an instance type with 800 Gbits/s of network bandwith in 2021. primarily virtual?—?and

Rich became co-author of the second edition of the Sun Performance Tuning book, to describe how it worked.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A quick check of basic performance statistics showed over 30% higher CPU consumption. How would you _time_ time?

We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded. So, we set out to build a fully hosted AWS database service based upon the original Dynamo design.

there’s a Python library for virtually anything a developer or data scientist might need to do. The most popular CM tools are DevOps focused, and, like DevOps itself, they’re declining: usage in the CM topic dropped significantly (-18%) in 2019, as did virtually all CM tools. Interestingly, R itself continues to decline.

In the first step we might reach this goal by combining the fastest mobility services through a digital platform; in the next, it might be a task fulfilled by Virtual Reality.
