Terms explanations
| New size - Size, in bytes, of the resulting compressed executable. Small = good |
| Ratio - ( New size / Original size ) * 100. Small = good |
| Speed - Decompression speed, in MB/s: The speed at which the original executable is unpacked into memory, at runtime, on a 1GHz processor. I.e.if the original executable's size was 15 MB and the Speed is 5MB/s, it would take 3 seconds on a 1GHz processor for the executable to be unpacked into memory. Large = good |
| Speed / Ratio - Decompression speed divided by compression ratio, then multiplied by 100. Large = good |
