what does it matter that it runs slowly, run it once and be done with it?
alternatively use the php tidy extension and avoid the file system and shelling
out altogether.
actually I'd imagine shelling out from a webserver process is the bottle neck
and not saving/reading
from the file system.
lastly I don't suppose you've heard of /dev/shm ?
and, er, no, I don't have experience with php://memory but you might try
searching for
other people's code:
