How can the script be optimized for better performance when generating avatars?

The script can be optimized for better performance when generating avatars by reducing the number of database queries and optimizing image processing functions. One way to achieve this is by caching the generated avatars to reduce the load on the server and improve response times. 

<?php
// Check if the avatar already exists in the cache
$avatarCache = 'avatar_cache/' . md5($email) . '.png';
if (file_exists($avatarCache)) {
    // Use the cached avatar if it exists
    $avatar = $avatarCache;
} else {
    // Generate the avatar if it doesn't exist in the cache
    $avatar = generateAvatar($email);
    // Save the generated avatar to the cache
    imagepng($avatar, $avatarCache);
}

// Output the avatar image
header('Content-Type: image/png');
readfile($avatar);

// Function to generate avatar
function generateAvatar($email) {
    // Generate the avatar image here
}
?>
