Apple Tells Devs to Use IPv6 As It's '1.4 Times Faster' Than IPv4 — Apple holds a lot of sway with what technologies developers use (e.g. Steve Jobs stance on Flash) so it’s interesting to see them pushing IPv6, HTTP/2, and TLS 1.3 hard. Improved routing and reduced NAT usage is cited for the ‘1.4 times faster’ claim around connection setup times.

Speculation in JavaScriptCore (or How Modern JS Engines Run Fast) — A long, technical post about speculative compilation and how it makes a dynamic language like JavaScript a lot faster than it might otherwise be (or was, pre V8!)

Migrating a 40TB SQL Server Database — A database administrator at Stack Overflow tells the tale of migrating over four years of traffic data (totalling almost 40TB) from one schema to another. This raises more questions than it answers (one being, why are they storing several years of traffic data in a live, relational database?) but it’s a neat writeup nonetheless.

Eliminating Cold Starts with Cloudflare Workers — No one likes cold starts – that delay when a function isn’t loaded, in memory, and ready to run. But Cloudflare thinks they have an optimization to eradicate them.. load the worker first thing during TLS negotiation. This only works because Workers’ load time is low in the first place, though.
