I have a whole lot of data in text form in a few dozen files. I read through this data and pick out pieces that I need to save, converting the format of those pieces to binary or flag bits as I go. During the processing, I must do lookups within the data that has already been read, in order to calculate certain pieces of the new data's effects. When everything is finished, I construct a couple of indices to the data and write the whole schmeer out to disk. As far as I can tell, the main things I'm exercising are disk i/o and the paging system (as I don't have enough memory to keep the whole thing resident).

The two HP runs, the drive and filesystem were not changed between the RH 7.2 run and the RH 8.0 run.
