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%

In the fourteen years that I've been working in the web performance industry, I've done a LOT of research, writing, and speaking about the psychology of page speed – in other words, why we crave fast, seamless online experiences. Queueing theory is the mathematical study of waiting lines, both real and virtual.

This would open up opportunities to leverage existing performance monitoring tools and dashboards, extend optimization tools like autoscalers and schedulers, and to build new kinds of carbon analysis and optimization tools and services. I published a paper and presentation in 2006 that discusses the complexities of measuring CPU utilization.

These front end frameworks provide various templates to interact with browser components and are compatible with various libraries which boost the performance while reducing the amount of code required. React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly.

For instance, Nielsen’s research conducted in 2006 showed that people read content on the Internet in an F-shaped pattern. Another area that has been showing huge potential is eye-tracking in the context of virtual reality. Including eye-tracking in the process of usability testing can offer many benefits for UX teams.

But first, a really quick summary of the original issue: In the last post I talked about how every time a CFG-enabled process allocates executable memory some Control Flow Guard (CFG) memory is allocated as well. For the process above where vmmap said there were 402.8 Additional wasted memory. Total: 41.763s, 1457.7 MiB, 67.7
