85 # We are trying to create roughly 50 or 100 holes in a file
86 # using random writes. Assuming a good distribution of 50 writes
87 # in a file, the file only needs to be 3-4x the size of the write
88 # size muliplied by the number of writes. Hence we use 200 * pgsize
89 # for files we want 50 holes in and 400 * pgsize for files we want
90 # 100 holes in. This keeps the runtime down as low as possible.
