using bdt+oo2reck:

Compressed 1 file, 4,339,674 => 16,546,064 bytes. Ratio 381.27%
Compression time: cpu 0.03 sec/real 2.79 sec = 1%. Speed 1.56 mB/s

Extracted 1 file, 16,546,064 => 4,339,674 bytes. Ratio 381.27%
Extraction time: cpu 0.00 sec/real 0.77 sec = 0%. Speed 5.63 mB/s

4,13 MB (4 339 674 bytes) >> 15,7 MB (16 546 306 bytes)

using QuickBMS and nfsshift.bms:

4,13 MB (4 339 674 bytes) >> 15,7 MB (16 543 104 bytes)

Edit:

A bit bigger input this time and here are the results:

Compressed 1 file, 332,106,505 => 1,904,256,950 bytes. Ratio 573.39%
Compression time: cpu 0.70 sec/real 126.43 sec = 1%. Speed 2.63 mB/s

Tested 1 file, 1,904,256,950 => 332,106,505 bytes. Ratio 573.39%
Testing time: cpu 0.75 sec/real 27.13 sec = 3%. Speed 12.24 mB/s

Always the Smart One Good Work Mate..
