In this post I'll look at the Linux kernel page table isolation (KPTI) patches that workaround Meltdown: what overheads to expect, and ways to tune them. Much of my testing was on Linux 4.14.11 Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar. and 4.14.12

This is why Lighthouse and Core Web Vitals specify First Input Delay (FID) and Total Blocking Time (TBT) metrics to measure site interactivity and input responsiveness. An additional way of identifying those bundles is to run a performance test in a browser or use WebPageTest , and check which bundles block the CPU main thread the longest.

As such, a micro-optimization is, again, how you probably need to fine-tune things on a low level to really benefit from it. As discussed in part 2 , that’s where QUIC is most likely to pay off anyway, and using a CDN is one of the key performance optimizations you can do. Tools and Testing. What Does It All Mean?
