What is Latency?
Latency in system design refers to the time it takes for a system to respond to a request or perform a task. It’s the delay between initiating an action and receiving a result. In computing, latency can occur in various aspects such as network communication, data processing, or hardware response times.
- Latency represents the delay between an action and its corresponding reaction
- It can be measured in various units like seconds, milliseconds, and nanoseconds depending on the system and application.
In network systems, latency can be influenced by factors like the distance between the client and server, the speed of data transmission, and network congestion. In data processing, it can be affected by the efficiency of algorithms, resource availability, and the architecture of the system.
Low latency Design Patterns
Low Latency Design Patterns help to make computer systems faster by reducing the time it takes for data to be processed. In this article, we will talk about ways to build systems that respond quickly, especially for businesses related to finance, gaming, and telecommunications where speed is really important. It explains different techniques, like storing data in a cache to access it faster, doing tasks at the same time to speed things up, and breaking tasks into smaller parts to work on them simultaneously.
