Performance tuning in msxsl/msxml

Hi,

I am using msxsl processor to transform xml to xml first and the same xml to 
text later. (loading same xml 2 times) In the first load i am getting xml 
output file and i have used xsl:key element here.

According to the requirement i have to do this twice. The input xml is large 
and i have to do this like 7 seven times to get data from seven different 
categories in the input xml. So i am loading the same xml document for 14 
times to get different outputs.

My questions are 
1) How can i keep the same xml document in memory to be used by other 13 runs 
?
2) With what parameter i can tune performance of msxsl. I had used vbscript 
along with it so have to stuck with only msxsl processor ?
3) I have to run this on the server having 4 CPUs and memory will be 2 GB and 
processor speed=800 Mhz. Can i optimize performance using CPU affinity factor 
? I have already made this as high priority process, what else can be done to 
get output faster.

I would be grateful if someone please inform me how to improve this 
performance issue. Thanks in the anticipation that i will get some hints.

I hope i am able to explain my question clearly and purposely i have not 
attached xsl and xml which are quite big. If my question is still not clear i 
will attach small version of input xml and my xsls.

Regards,
Dipesh
