99 # We are trying to create roughly 50 or 100 holes in a file

101 # in a file, the file only needs to be 3-4x the size of the write
102 # size muliplied by the number of writes. Hence we use 200 * pgsize
103 # for files we want 50 holes in and 400 * pgsize for files we want
104 # 100 holes in. This keeps the runtime down as low as possible.
