How to speed up PHPMailer?

[d-flyer]

Hi all,

I am testing with the PHPMailer class, I have my email 150 times in my database and the following code

// Send the emails in this loop. 
  	$name = $row_rsMailUsers->name;
	$email = $row_rsMailUsers->email; 
  if($row_rsMailUsers->MailType == 'html') 
  { 
    $mailer->Body = str_replace('{MEMBER_NAME}', $name, $htmlBody); 
    $mailer->IsHTML(true); 
    $mailer->AltBody = str_replace('{MEMBER_NAME}', $name, $textBody); 

$mailer->AddAddress($email, $name ); 
  } 
  else 
  { 
    $mailer->Body = str_replace('{MEMBER_NAME}', $name, $textBody); 
    $mailer->isHTML(false); 
	$mailer->AddAddress($email, $name ); 
  } 
	$mailer->Subject = "Testing";
	$mailer->From  = "[e-mail]";
	$mailer->FromName = "Me testing";
	$mailer->IsSMTP(); // telling the class to use SMTP
	$mailer->Host = "smtp.mysite.com"; // SMTP server */

  if(!$mailer->Send())
	{
	   echo "There was an error sending the message";
	   exit;
	}
	echo "Message was sent successfully";
	echo "Mail sent to: ".$row_rsMailUsers->name."<br />"; 
	$mailer->ClearAddresses(); 
  	$mailer->ClearAttachments(); 

And I find it very slow?
Anyway to speed this up?
Has PHPMailer an maximum number of emails to send to?
