Hardware gets better, sure. Cennydd also makes the case that performance also has an impact on energy consumption: In 2016, video, tracking scripts and sharing buttons caused the average website to swell to the same size as the original version of Doom. Ballooning bandwidth and storage have fostered complacency that we can do without.

I also wrote about these topics in detail for my recent [Systems Performance 2nd Edition] book.

The original motivation for FB was due to different hardware generations, especially between regions/data centers. And I agree that in the modern age of cloud and huge flash storage, the vast majority of companies will never need to consider doing this in prod, but there is always a chance of its need. AFAIK Facebook does this.

At the time of the last Confluence run, the gap had stretched to nearly 1000 APIs, doubling since 2016. Chrome has missed several APIs for 3+ years: Storage Access API. is access to hardware devices. This allows customisation and use of specialised features without custom, proprietary software for niche hardware.

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.

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. I'd expect between 0.1%
