Why is Latency a Critical Metric in Assessing Computer System Efficiency?

Latency is an important factor when looking at how well a computer system works. It measures the time it takes from when you ask for something until you get the first answer.

Why Latency Is Important:

  • User Experience: Low latency makes users happier, especially in situations that need quick responses, like online games or video calls. If you're playing a fast game and there’s a noticeable delay, it can mess up your reaction time and ruin the fun.

  • Performance Insight: Latency helps us check how well a system is running. For example, if a web server can handle a lot of users but has high latency, it could still be slow. This means web pages take longer to load, which isn’t good.

  • Benchmarking: When comparing different systems (also known as benchmarking), looking at latency with throughput gives us a clearer picture of how a system works. A system might handle a lot of tasks at once (high throughput) but if it has high latency, it can create delays or slowdowns.

In short, making sure latency is low not only helps improve performance but also makes user interactions better across different systems.
