    Description

      UDAF take significantly longer to process than built in functions – as much as 2x. Using a profiler, find the points that may be improved. Use of shared_ptr is one such. It turns out shared_ptr can get expensive in tight loops which we do with userData. I don't know if we can get rid of it here. More analysis is needed. Other optimizations need to be considered and perhaps extended to the entire aggregate system.
