Provides:
amount of compressed data
logical size of compressed data (how much it would have taken uncompressed)
compression ratio (logical size : total ARC size)
Overhead (space consumed for compression headers)
Example output:
ARC: 31G Total, 18G MFU, 9067M MRU, 2236K Anon, 615M Header, 2947M Other
25G Compressed, 54G Uncompressed, 1.76:1 Ratio, 2265M Overhead
