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. Maintenance Without MayhemWhat happens when one of your servers/data centers needs a tune-up?

The main objective of this post is to share my experience over the past years tuning MongoDB and centralize the diverse sources that I crossed in this journey in a unique place. The CFQ works well for many general use cases but lacks latency guarantees. Spoiler alert: This post focuses on MongoDB 3.6.X

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!).

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.

Hyperscale achieves high performance from each compute node having SSD-based caches which helps minimize the network round trips to fetch data. There is a lot of awesome technology involved with Hyperscale in how it is architected to use SSD-based caches and page servers. Azure SQL Managed Instance Performance Considerations.

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)). Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. This is true, but only to a relatively limited extent.

Today we’re excited to announce that we’ve launched yet another POP location to help further supercharge our network’s content delivery speeds. The next closest active POP location to Bucharest was Istanbul which was still almost 900km away; this distance adds up in terms of latency. What’s Next?

Today we’re excited to announce that we’ve launched yet another POP location to help further supercharge our network’s content delivery speeds. Although both countries are relatively close to one another, they are separated by a distance of approximately 500km, which adds up in terms of latency. What’s Next?

VPC Endpoints give you the ability to control whether network traffic between your application and DynamoDB traverses the public Internet or stays within your virtual private cloud. Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases.

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”. and lower), this typically takes two network round trips.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.
