I'd like to know the impacts of setting the Policy Server thread
pool to 128.
If you defined a thread pool of 128, then the
Policy Server will start 128 threads.
To determine if the 128 are needed, you need to bench mark
your environment and see if it fits your Business Needs.
Remember that as 32bit application, the Policy Server will
split its memory among 128 thread instead of the out of the
box 8 configured.
