At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. 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. AWS called this [enhanced networking]. The first was c3.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. top(1) showed that only the Cassandra database was consuming CPU. This server is spending about a third of its CPU cycles just checking the time! Other EC2 instance types, such as C5 or M5, use the AWS Nitro Hypervisor.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? It used to provide an insight into how quickly the server outputs any data. What does it mean?
