| Size (GB) | c.f | Size (GB) | c.f | Time (hr) | |
| Uncompressed | 294 | 1 | 294 | 1 | |
| SlimGene | 57.0 | 5.16 | 16.2 | 18.15 | 7.39 |
| SAMtools | 89.5 | 3.28 | 32.8 | 8.96 | 10.79 |
The size of the entire uncompressed dataset is 294 GB. SlimGene compresses GAhum in 7.39 hours for a compression factor of 5.15×. On the other hand, SAMtools provide a compression factor of 3.28× in 10.79 hours. In the absence of quality values (all bases have an identical quality), the advantage of SlimGene is magnified.
