Based on tests with various randomly selected images, packJPG reaches compression ratios between those of PAQ8L and PAQ8M.
It is a lot faster than both of them. On average, packJPG needs about 90% less time for compression and decompression of a JPEG file than PAQ8L does and about 93% less than PAQ8M does.
