Additional Information
The specified Focal Statistics tool does demonstrate benefits from increasing the Parallel Processing Factor (PPF) environment setting, either way it is set. However, the benefit is only evident once the performance gain from parallelization exceeds the cost incurred to initiate splitting up the analysis and aggregating the results from each process into a final result. For the Focal Statistics tool, the optimizations made to the tool for the standard 3x3 cell 'Rectangle' neighborhood and simple statistics such as 'Mean' or 'Sum' make it difficult for parallelization to improve things. However, with non-rectangle neighborhoods, larger neighborhoods, and certain statistical types, performance improvements with higher settings for the PPF environment can be demonstrated.Steps to Reproduce
