Requests Fewer server requests improve site speed and energy efficiency. This can be achieved by bundling files, using CSS sprites for images, and implementing Con-tent Delivery Networks (CDNs). 

Recommendations:

• Bundle CSS and JavaScript:
  Reduce load time by minimizing file requests.
• Use sprites:
  Consolidate icons and small images into a single file to limit server calls.
• Leverage CDNs:
  Deliver static content from servers closer to the user to enhance speed and efficiency.
