Caching is the way to go. You can either make your XSP cacheable (e.g. by using ExpiresValidity) or configure the pipeline to be cacheable ("expires 1 hour" or similar).


Dotring such a huge XML tree in session will probably lead fast to an OutOfMemoryError.

i have a .xsp that read from a database and create a .xml file that
describe a tree, then the data from this xml are transformed to a
javascript tree

the problem is that i need the xml data from the database in each request
to create the tree (navigation tree) but some times those data produce a
.xml with 7000 - 10000 nodes. so i have to wait some minutes to ge a
responce.

my question is:

where can i store temporary the produced XML (i can not use file system)
so not to have to call .xsp in each request?
is it possible to store the tree in SESSION ?

WriteDOMSessionTransformer should be your friend:
