As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks. If your average visitor is on a fast cabled or cellular network, they probably won’t benefit from the new protocols all that much. Two-way latency is often called round-trip time (RTT). Congestion Control.

It's time once again to update our priors regarding the global device and network situation.

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. 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.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two.

This work is latency critical, because volume IO is blocked until it is complete. Physalia is designed to offer consistency and high-availability, even under network partitions. And, of course, it is designed to minimise the blast radius of any failures that do occur. Larger cells have better tolerance of tail latency (e.g.

The goal is to produce a low-energy hardware classifier for embedded applications doing local processing of sensor data. Of course analog signalling comes with a whole bunch of challenges of its own, which is one of the reasons we tend to convert to digital. So decision trees are essentially networks of threshold functions.
