Note: C. time and D. time stand for compression and decompression time (s), respectively. The results in bold correspond to the best compression performance among the different algorithms. We use the International System of Units for the prefixes, that is, 1 MB and 1 kB stands for 10⁶ and 10³ bytes, respectively.

^aDenotes the cases where GRS outperformed GReEn. In these cases, i.e. L.pneumohilia and S.cerevisiae, the compression achieved by GReEn is 495 kB and 304.2 kB, respectively.

^bDenotes the cases where GDC-advanced outperformed GDC normal.
