Improving WebView2 Initial Load Time

The initial load time for WebView2 can be slow due to several factors. Here are some common reasons and potential solutions:

1. Initialization Overhead: The first time WebView2 initializes, it can take longer because it needs to set up the environment. This includes creating the user data folder and loading necessary components.

2. File I/O Operations: During the first load, WebView2 performs several file I/O operations which can slow down the process. Ensuring your storage is fast (e.g., using an SSD) can help mitigate this.

3. Antivirus Interference: Sometimes, antivirus software can slow down the initialization by scanning the files WebView2 needs to load. Temporarily disabling the antivirus (for testing purposes) can help identify if this is the issue.

4. Proxy Settings: Proxy settings can also affect the load time. Disabling proxy settings in Windows might improve performance.

5. Pre-Initialization: You can pre-create an invisible WebView2 instance during your application's startup. This way, when the user actually needs to see the WebView2 content, it will load faster.

6. Cache Management: Managing the cache size and ensuring it is not too large can also help improve performance.

7. Synchronous Loading: Loading CSS and JavaScript files synchronously can help speed up the page load time by ensuring elements are loaded without waiting for each other.

Implementing these strategies should help improve the initial load time of WebView2 in your application. If you have any specific configurations or further questions, feel free to ask! Message has links.
