Performance issues while exporting Simulation to .CRF

Hi, we are currently using ArcGIS Pro to simulate all areas affected by heavy rain and flooding within our jurisdiction.
We export the results to a .CRF file with a timestamp every 15 minutes, but we would also like to export the maximum values per cell throughout the entire simulation.
To achieve the second scenario, we need to set the export interval to every 2–5 seconds and then use a “Maximum” summary statistic to export the maximum values from each slice.

The problem we now face is that the export performance of the .CRF file is extremely poor. If we simulate for 5 hours and create an export every 5 seconds, we end up with 3,600 slices in the .CRF file. As soon as the flood simulation export is complete, up to 4 additional dimensions are automatically calculated for each slice, but ArcGIS Pro freezes throughout this process.

Especially when we set the export interval to 1–2 seconds, I have to wait several days before ArcGIS Pro stops freezing.

Hey @Fabian_Schroeer 

So just out of curiosity, why does the export interval have to be so quick, 2-5 seconds would create an immense amount of data, which more than likely directly contributes to the time that ArcGIS Pro is taking to do these calculations.

If possible, I'd move the interval to 60+ seconds or even 3-5 minutes, how are you calculating the maximum summary statistic? Using the Aggregate tool?
