I have used XSLTProcessor to receive XML data:

$atb = new XSLTProcessor();

Often it takes a few seconds the data to load. I understood that there is a faster way to load the information. The current speed is like this: http://time-time.net/time/new-york-new-york-usa.php

which is in most of the cases too slow.

Do you have any tips where to look for information?
