What are some best practices for optimizing the performance of a PHP website with multiple requests and large file sizes?

To optimize the performance of a PHP website with multiple requests and large file sizes, one best practice is to enable caching for static assets and database queries. This can help reduce the load on the server and improve response times for users. Additionally, using asynchronous processing for tasks that do not need to be completed immediately can help free up resources for handling other requests more efficiently. 

// Enable caching for static assets
header('Cache-Control: max-age=3600');

// Enable caching for database queries
$cacheKey = 'cached_data';
$cacheTime = 3600; // 1 hour
if ($cachedData = apcu_fetch($cacheKey)) {
    // Use cached data
} else {
    // Fetch data from database
    $data = fetchDataFromDatabase();

    // Store data in cache
    apcu_store($cacheKey, $data, $cacheTime);
}
