You could try echo-ing it out in "chunks" instead of waiting until the very end. echo/print has to send the data "out" through the very narrow pipe to Apache -> the browser If you send every little snippet one tiny piece at a time, you waste resources. If you wait until the end and send out some huge monster string, you waste resources. Find the balance if you can. Depends on your hardware/bandwidth exactly where optimum is. -- Like Music? http://l-i-e.com/artists.htm
