File sizes are shown in megabytes and run times in minutes. ReCoil, Coil and 7-zip were given 2 GB of RAM, while bzip2 was run with the compression-level = 9. Both ReCoil and Coil used 7-zip as a post-processing compression step, this step was included in the timings. Decoding time for ReCoil was less than 5 minutes for all datasets, including the 7-zip uncompress step.
