Two possibilities. 1. By not processing the extension point, and not picking up the slow xpath processing property accessor. Instantiate a fast processor and just use it. 2. Use the hinting system to specify that you want to use the fast property accessor. Not sure the expression api allows us to pull this one off. > > By the time you can use a profiler, the design is done and coded in > detail.

Hmmm, all the code I write must be really slow then because I have always been able to make it orders of magnitude faster with just a profiler. > > Cheers > Andrea > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
