# App speed

## Why is the speed of my app slow?

The speed of your mobile app is directly influenced by the response time of your website’s database. Since AppMySite **fetches data in real-time using REST APIs**, any delays in your website's response will impact your app’s performance.

{% hint style="warning" %}
Understanding response time

* AppMySite does not store your website data but retrieves it dynamically via REST APIs.
* If your website loads quickly in a browser, it doesn’t necessarily mean the app will load at the same speed.
* The database response time is the key factor affecting app performance.
  {% endhint %}

### **Factors that may slow down your app**

Several factors could be impacting the database response time and slowing down your app:

* Lack of image optimization on your website. Images take longer to load and slow down the response time of your website’s database.
* The location of your server. We suggest using CDNs to ensure your website loads fast anywhere in the world.
* The number of plugins on your website. Too many plugins can slow down the response time of your website, especially if they make too many requests to your WordPress database.
* The reliability of your website host. We suggest you invest in a reliable hosting partner that can guarantee a certain level of database response time. 

{% hint style="warning" %}
If your app is built using the Web-to-App solution, the app simply renders your website inside a web-view interface. The app’s speed depends entirely on your website’s loading speed.
{% endhint %}

{% hint style="success" %}
How to diagnose performance issues:

* Visit the Performance module in your AppMySite account for optimization tips.
* Use the Connectivity troubleshooter to check your app's response time. If the results show unusually high response times, you may need to optimize your website.

## 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.appmysite.com/app/performance/app-speed.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.
