So what exactly do those tweaks do?
they memory content is pushed to the pagefile, so onto the hdd, which frees up extra system memory to be used for the pi calculations?
As a result less of the calculation results of the benchmarks need to be moved to the pagefile cause the memory is full? How big are the files that the pi benchmark creates during a 32m run? I dont mean how many files overall but how many files and of what size does the benchmark create that need to remain buffered to create the final result?

How exactly does the pi app work?
it creates temp files in memory?
Are they deleted or ready to be deleted once the iteration finished?
Does the pi app overwrite its older temp files or keeps going up and up memory address wise until the mem is full and then even writes temp files to the pagefile on the hdd?
