SOAP Running Slow

[srikanth1184]

The following code is taking 10 sec to get the response. Am i missing any thing?

<?
require_once 'SOAP/Client.php'; 

$wsdl_url =  

  'http://soap.amazon.com/schemas3/AmazonWebServices.wsdl'; 
$WSDL     = new SOAP_WSDL($wsdl_url);  

$client   = $WSDL->getProxy();  

$params   = array( 
    'manufacturer' => "Addison Wesley", 
    'mode'         => 'books', 
    'type'         => 'lite', 
    'tag'          => 'Design Patterns', 
    'devtag'       => '' 
); 

$books    = $client->ManufacturerSearchRequest($params); 


ECHO "<PRE>"; 
PRINT_R($books); 
ECHO "</PRE>"; 
?>
