> "The old dispatcher is around 10% faster and consumes less memory (!!!) then the new
one. The new one is using AXIOM to create the final document which supposed to be faster then
DOM, but it is not.
> I switch the contract processing from DOM to AXIOM to finally have SAX.
> Some sidenotes of my profiling sessions: - we use as testing ground a dedicated linux
box which is basically a replica of - the side is made
with cocoon 2.2 and "old" dispatcher cocoon 2.2 block (which is the same as we use here in
forrest projects). - The app is running on a tomcat6 and java6. - We using jmeter to have
an incremental test run on concurrent threads (starting with 5 to 90 concurrent threads).
