79 # We are trying to create roughly 50 or 100 holes in a file
80 # using random writes. Assuming a good distribution of 50 writes
81 # in a file, the file only needs to be 3-4x the size of the write
82 # size muliplied by the number of writes. Hence we use 200 * pgsize
83 # for files we want 50 holes in and 400 * pgsize for files we want
84 # 100 holes in. This keeps the runtime down as low as possible.
