How to reproduce?

1. If a connection is established, it will be closed after 15 seconds, and the idle time cannot be extended. In my situation, multiple requests are made to the same domain and require a persistent connection, meaning the connection should be maintained even after 15 seconds. Is there another property that can be used to achieve this?
2. Prior to establishing a connection, if multiple requests are made, each request takes time to establish a connection. Is there a way to avoid this and reduce the time taken for all requests? For instance, in the screenshot below, 4 requests are made to the same domain before the connection is established, and each request takes around 2 seconds to establish a connection. Is there a way to decrease this time?

But once the connection is established, for other requests it didn't consume much time to establish the connection, here its reused.
