Sascha, the reason why 1.3.0pre4 might be faster would not be because of the missing namespace, but most likely because of missing self-heal. can you try with 'option self-heal off' in the unify section? are the test results same for multiple runs too? avati 2008/1/18, Sascha Ottolski <ottolski@xxxxxx>: > > Hi Folks, > > I'm wondering if anyone might have some general advices if I miss > something important in my test setup.
