Anyway, the original version spends half of it's time writing to stdout, verify by replacing
OutputStream stream = new BufferedOutputStream(System.out);
OutputStream stream = new BufferedOutputStream(new FileOutputStream("./mandel_out"));

"1. Each program is run and measured at the smallest input value, program output redirected to a file and compared to expected output. As long as the output matches expected output, the program is then run and measured at the next larger input value until measurements have been made at every input value."
The measurements are not made by typing each program command line into a terminal window.
