How can the PHP-side processing be optimized for faster email delivery when using PEAR::Mail_Mime or the mail() function?

To optimize PHP-side processing for faster email delivery when using PEAR::Mail_Mime or the mail() function, you can batch multiple emails into a single request to reduce overhead. This can be achieved by storing email messages in an array and sending them together in a loop. Additionally, make sure to properly configure your email server settings for efficient delivery. 

// Example code for batching emails using mail() function
$to = array('recipient1@example.com', 'recipient2@example.com');
$subject = 'Subject';
$message = 'Message';
$headers = 'From: sender@example.com';

foreach ($to as $recipient) {
    mail($recipient, $subject, $message, $headers);
}
