How can server speed and load impact the efficiency of PHP scripts embedded with JavaScript for banner display?

Server speed and load can impact the efficiency of PHP scripts embedded with JavaScript for banner display by causing delays in loading the banners, leading to a poor user experience. To improve efficiency, one solution is to optimize the server performance and reduce the load time of the PHP scripts. This can be achieved by implementing caching mechanisms, optimizing database queries, and using content delivery networks (CDNs) to serve static assets like JavaScript files. 

<?php
// Code snippet to implement caching mechanism for banner display
$cache_key = 'banner_cache';
$banner_data = get_transient($cache_key);

if ($banner_data === false) {
    // If banner data is not found in cache, fetch it from database or API
    $banner_data = fetch_banner_data();

    // Store banner data in cache for future use
    set_transient($cache_key, $banner_data, 3600); // Cache for 1 hour
}

// Display banner using the fetched data
echo '<div id="banner">' . $banner_data['content'] . '</div>';
?>
