Hi, --lowmem and --subset work for reducing memory footprint for projection data, and --division for memory usage of reconstruction calculation. SetProjectionSubsetSize() does not correspond to --division but to --subset flag. If you read the code, you will find without --lowmen the reader is updated before other part of the pipeline being executed; whereas with --lowmen flag it is updated together with the pipeline, thus is streamed.
