The POP is strategially located within the country and lowers latency overall. KeyCDN is always on the lookout for ways to minimize latency and accelerate asset delivery worldwide. For more POPs planned, check our current network for a list of both active and planned edge server locations. Hola Mexico!

To this end, we developed a Rapid Event Notification System (RENO) to support use cases that require server initiated communication with devices in a scalable and extensible manner. This separation allows us to tune system configuration and scaling policies independently for different event priorities and traffic patterns.

Enter the concept of Content Delivery Networks (CDN) with Multiple Origins Load Balancing. Just like how a traffic cop ensures cars flow smoothly at an intersection, a Load Balancer makes sure data moves efficiently across the network. Each of these is managed by a separate microservice that resides on its own origin server(s).

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).

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”. Websites would magically become 50% faster with the flip of a switch!

Next, we’ll look at how to set up servers and clients (that’s the hard part unless you’re using a content delivery network (CDN)). This difference by itself doesn’t do all that much (it mainly reduces the overhead on the server-side), but it leads to most of the following points. Server Sharding and Connection Coalescing.

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. I've refuted many benchmarks by showing that they would require a network throughput that would far exceed the maximum network bandwidth (off by, for example, as much as 10x!).

There is a lot of awesome technology involved with Hyperscale in how it is architected to use SSD-based caches and page servers.

Making queries to an inference engine has many of the same throughput, latency, and cost considerations as making queries to a datastore, and more and more applications are coming to depend on such queries.
