    Original size | 100 GB
    Compressed size | 47.8 GB (2.091 ratio)
    Transfer speed | 1 Gbps (125 MB/s)
    Original transfer time | 100 GB / 125 MB/s = 800 seconds
    Compressed transfer time | 47.8 GB / 125 MB/s = 382.4 seconds
    
    Compressor | Snappy
    Compression ratio | 2.091 ratio
    Compression speed | 565 MB/s
    Decompression speed | 1950 MB/s
    Compression time | 100 GB / 565 MB/s = 177 seconds
    Decompression time | 47.8 GB / 1950 MB/s = 24.5 seconds
    
    Transfer time w/o compression | 800 seconds
    Transfer time with compression | 177 + 382.4 + 24.5 = 584.9 seconds
