hi andrew i think you understand my problem a little,
but if 100 user load this query at the same time, the two mysql server
had a lot to do!
so i think to cache this query as xml to the application server local
make thinks faster,
but, i would like to have the same performance to read this xml document
as read the query from mysql server...
i dont know why php is so slow to read the xml file...

From my understanding of your question, your message (included

I've CC'd on this reply. If you haven't yet, please subscribe there

If I'm misunderstanding and you're asking a PHP-related question,
please rephrase your question.
I understood the question to be how to improve performance by caching
MySQL results into an XML document (which, given that it was posted
here) within a PHP script. Perhaps this is not the correct
interpretation, but if so it would be relevant.
However, I'm not sure I'd spend time trying to devise a "fast" XML
cache for a query that only took 0.3 seconds to execute. By itself,
that isn't bad performance unless this is a query that is called
frequently by several concurrent users. Personally, I'd look into ways
to improve the execution of the query itself in MySQL (making sure the
query is sargable and improving indexes, etc.) until I thought I had
exhausted everything there.
Just my 2 cents.
Andrew
