Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

This is a set of best practices and guidelines that help you design and operate reliable, secure, efficient, cost-effective, and sustainable systems in the cloud. Storing frequently accessed data in faster storage, usually in-memory caching, improves data retrieval speed and overall system performance. Beyond

As developers, we rightfully obsess about the customer experience, relentlessly working to squeeze every millisecond out of the critical rendering path, optimize input latency, and eliminate jank. On top of this foundation, we add layers of caching, prerendering and edge delivery optimizations — not the other way around.

This reduction in latency ensures that applications and websites provide a more rapid and responsive user experience. Efficient memory management, including optimizing query caches and buffer pools, can help strike the right balance between memory consumption and query response times.

While dynamic serving provides simplicity in implementation, it imposes significant time costs due to the computational resources required to generate the pages and the latency involved in serving these pages to users at distant locations. The shorter the TTFB, the better the perceived speed of the site from the user’s perspective.

Best practice for DBAs is really to just treat ReportServer and ReportServerTempDB like any other user database. Disk latency for ReportServer and ReportServerTempDB are very important. Caches of report results are stored in the ReportServerTempDB database and I/O performance can become an issue here.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. For high-pressure points like animation, it’s best to do nothing else where you can and the absolute minimum where you can't.

On the other hand, if done at design, it is probably the best solution because it will allow the application to define the sharding rules and can also optimize the different data sources using different technologies for different uses. However, if we can already identify some benefits here, that will be an interesting result.

Today, I'm excited to announce the general availability of Amazon DynamoDB Accelerator (DAX) , a fully managed, highly available, in-memory cache that can speed up DynamoDB response times from milliseconds to microseconds, even at millions of requests per second. Adding caching when your app is already experiencing load is not easy.

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 would, however, be hard-pressed even today to find a good article that details the nuanced best practices. This is because, as I stated in the introduction to part 1 , much of the early HTTP/2 content was overly optimistic about how well it would work in practice, and some of it, quite frankly, had major mistakes and bad advice.

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”. We will discuss these features in more depth later in this article.
