# Performance

The **Performance** tab provides a consolidated view of application responsiveness by grouping five key dimensions of user experience for the selected web application:

* [Time lost](/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance/time-lost.md) – Quantifies total productivity lost to slow page loads, transactions, and errors.
* [Page loads](/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance/page-loads.md) – Measures how quickly application pages load and highlights frustrating delays.
* [Reliability](/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance/reliability.md) – Tracks error rates across sessions and identifies stability issues.
* [Transactions](/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance/transactions.md) – Monitors the duration and success of key user actions across the app.
* [Benchmark](/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance/benchmark.md) – Compares your application's performance against cross-customer benchmark data.

This tab helps you quickly diagnose performance problems and prioritize improvements.

Use the predefined **Investigate more** drill-downs and contextual **Insights** panels to analyze root causes without leaving the page.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.nexthink.com/platform/user-guide/applications/monitoring-applications/monitoring-web-applications/performance.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
