Aggregated Results

Compression Rate

Overall, WinRK was the champion at compressing the filesets. It had an average compression rate of 24.8%. It was 5.5% better at overall compression than its closest rival, SBC Archiver which had an average compression rate of 23.5%.

The poorest compressors overall, at default settings, weregzip and ARJ32. They only had average compression rates of about 12.7%.

Compression Speed

However, gzip was the undisputed speed champion. It only took just over 2.5 minutes to completely process the complete fileset collection which weighed in at over 1.6GB. It was over 16% faster than the runner-up, ARJ32.

The other compressors were pretty slow at their maximum compression settings. However, WinRK was extremely slow. It took over 2.5 hours to compress the entire fileset collection.

Compression Efficiency

The compression efficiency rating is a simple way to evaluate the efficiency of each data compressor. This way, we can see which compressor can save the most space in the least time.

Please note that a higher efficiency rating does not mean the compressor is better. It just means the compressor has a better compression-to-speed ratio. A more efficient compressor is, of course, always more desirable than a less efficient one.

The most efficient data compressor for the aggregated results was gzip. Its super-fast compression speed, coupled with its average compression rate allowed it to become the undisputed overall efficiency champion. ARJ32 was close behind, and more than twice as efficient as its nearest rivals, bzip2 and StuffIt.

The other compressors were less efficient, but no one could beat WinRK. Although it was a really good compressor, its incredibly slow compression speed totally killed its efficiency ratings. Even WinAce was over 5X more efficient than it!
