# Capacity Usage (legacy)

{% hint style="info" %}
This section covers the capacity metric system, which has been replaced with the workload metric. Please see this section for [up-to-date information.](/account-and-marketplace/account-and-billing/pricing-plans.md)
{% endhint %}

This section of the editor shows your app's capacity usage and real time metrics. These metrics are useful for pricing purposes and assessing app performance.

## Page load metrics

These charts show metrics about your pages loading time. This data is gathered over the latest page loads by all your users over the last 60 minutes.

### Metric to display

You can see three different kinds of metrics:

* **Page load duration: render complete** The time in milliseconds from when the Bubble server first receives a request for a page, to when all elements on the page are finished rendering. This includes the time it takes for the server to process the request, latency between the server and the web browser, the time it takes to load all client-side javascript and css, and the time it takes the browser to draw the elements on the page.
* **Page load duration: data loaded:** The time in milliseconds from when the Bubble server first receives a request for a page, to when all the elements on the page are rendered, and all the dynamic data required by above-the-fold elements is fetched and displayed. This is equivalent to the "Page Loaded Above Fold" data source. It includes all the time included "Page load duration: render complete", plus the time to load data (such as Repeating Groups lists).
* **Page load: count of data items required:** This is the number of data Things loaded during the period tracked by the "Page load duration: data loaded" metric. It's an estimate of the total data the page requires in order for all the above-fold elements to finish loading. It's useful for investigating the impact that loading data (for instance, in Repeating Groups) is having on page load times.

### Percentile

You can choose to show averages over the best X percents. The best 1% will show the best performance, while 99% will show all situations.

# Agent Instructions: Querying This Documentation

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://manual.bubble.io/help-guides/maintaining-an-application/performance-and-scaling/capacity-usage.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
