This enables customers to serve content to their end users with low latency, giving them the best application experience. In 2008, AWS opened a point of presence (PoP) in Hong Kong to enable customers to serve content to their end users with low latency. Since then, AWS has added two more PoPs in Hong Kong, the latest in 2016.

These devices feature: Eight slow, big.LITTLE ARM cores (A75+A55, or A73+A53) built on last-generation processes with very little cache. For example, let's say you send more HTML and less JavaScript, or your serving game is on lock and all critical assets load over a single H/2 link. 4GiB of RAM. Qualcomm has some 'splainin to do.

A CDN, or Content Delivery Network, is a network of servers strategically positioned across various locations to expedite content delivery to users based on their geographic location.These patterns split into two main forms of traffic:Static Traffic: When a user request targets static content, the CDN first checks its cache.

The browser caches the results of these lookups, but they can be slow. This enables the browser to get ahead of the game and do more work in parallel, decreasing the overall load time. You might think of a prefetch as being a bit like adding a file to the browser’s cache. When Should I Use dns-prefetch ? The as Attribute.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The fastest Androids predictably remain 18-24 months behind, owing to cheapskate choices about cache sizing by Qualcomm, Samsung Semi, and all the rest. The Moto G4 , for example.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.

Amazon ElastiCache is a fully managed, in-memory caching service for customers to optimize the latency, performance and cost of their read workloads. For example, Scopely has built their gaming platform with DynamoDB as their primary datastore, while using Amazon RDS where they need complex query support.

Redis's microsecond latency has made it a de facto choice for caching. Four years ago, as part of our AWS fast data journey, we introduced Amazon ElastiCache for Redis , a fully managed, in-memory data store that operates at microsecond latency. Whether it is gaming, adtech, travel, or retail—speed wins, it's simple.

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”. Many sources claim that HTTP/3 is built on top of UDP because of performance.
