Ok, now i did some “clean up” on the code… did create some functions, have removed duplicated code, and add new features like “Requests per second“. Now i think is just fix any bugs that we will find, but the features for this particular tool are done.
Take a look:

FEATURES:
– Number of requests per block range (Reads and Writes);
– Total bytes (reads and writes), per block range;
– Percentage per block range;
– Bandwidth per block range (per second);
– Requests/second (per block range);
