Notes:
- CxB is the number of independent blocks a file was splitted
- MB/s is the speed measured in 1,000,000 uncompressed bytes per second
- all averages are calculated from the un-rounded values
- the average ratio & bits are calculated by the arithmetic mean
- the average speed is calculated by the harmonic mean
