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.

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! Or even on a plane.

Investigating weird Chrome performance problems is literally my job so we started chatting. I then looked in the “Virtual Memory Snapshots” table at the Working Set column. The difference is dramatic: The performance of scanning the memory in the normal mode is quite consistent, taking about 0.2 The answer is later in this post.

The Problem Of Unpredictable Performance. At the same time, we have a widening performance gap. Low-end phones on the other hand are getting cheaper , making the mobile internet accessible to demographics that previously maybe couldn’t afford it. The performance of the user’s device is completely unpredictable.
