title: "Response Time Check"
description: "In addition to pure availability, speed is crucial for user experience. The Response Time Check measures how long your server takes to respond to a request."

## What is measured?
We typically measure the **Time to First Byte (TTFB)** as well as the time for the complete transfer of the HTML document.

## Configuration
You can set thresholds for warnings:

- **Threshold (ms)**: If the response time exceeds this value (e.g., 2000ms), an alarm is triggered or the status is marked as "Degraded", depending on configuration.

## Analysis
In the monitor details, you will find charts showing the development of response time over time. This helps you to:

- Identify performance bottlenecks at specific times (e.g., during backups).
- See the impact of code deployments on speed.
