Which of the following describes how Mashup Links impact page load?

Mashup Links provide a way to integrate external content or applications within a Salesforce page without significantly impacting the main page load. When implemented correctly, they allow for a seamless user experience where the primary content loads independently of the external resources. This means that the presence of Mashup Links does not inherently delay or hinder the loading of the main page components.

By functioning as embedded content that can load independently, Mashup Links ensure that the primary content is displayed quickly while the external elements can continue to load in the background. This allows users to begin interacting with the page without waiting for all resources to finish loading, which contributes to a faster and more responsive user experience.

In contrast, other options suggest that Mashup Links either delay loading, require more resources, or block other content, none of which accurately reflect how they function in a typical setup within Salesforce. By promoting efficient loading mechanisms, Mashup Links enhance the overall performance of the page.
