It’s much easier to reach performance goals when the code base is fresh or is just being refactored.

Microservices fundamentally change a lot of assumptions current cloud systems are designed with, and present both opportunities and challenges when optimizing for quality of service (QoS) and utilization. Smaller microservices demonstrated much better instruction-cache locality than their monolithic counterparts.

On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. Therefore any programming abstraction must be low latency and the kernel needs to be kept off the path of persistent data access as much as possible.

The main reason is because it decreases the latency to the user where they are located by serving your images from a POP physically closest to them. The Cache Enabler plugin then delivers WebP images based to supported browsers.

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. Spurious reports of "10x worse" performance merit intense scepticism.

This prevents code reuse across databases. Go to step 1 if more chunks present. This way, log event processing can resume event-by-event afterwards, eventually discovering the watermarks, without ever needing to cache log event entries. Ultimately, we decided to implement a different approach to handle dumps.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”.
