Speed up XML parser?

[irock]

Hi, sorry for the long title. I was wondering. I have a page that needs to parse about 12 XML datafeed in real-time. Is this just too much for a simple PHP parser to handle? When I tried to load this page, the page is so slow. Is there anyway to speed this up?

Thanks much.

irock,
The only thing that I can think of is if you are parsing the xml for data within the program, and not to display to the user is to use multi-threading. I'm not sure if PHP has that ability, but .net does.
What are the sizes of the xml feeds that come back?
