bzip3
A better, faster and stronger spiritual successor to BZip2. Features higher compression ratios and better performance thanks to a order-0 context mixing entropy coder, a fast Burrows-Wheeler transform code making use of suffix arrays and a RLE with Lempel Ziv+Prediction pass based on LZ77-style string matching and PPM-style context modeling.
Like its ancestor, BZip3 excels at compressing text or code.
Alternatively, you might be able to install bzip3 using your system's package manager:
First, I have downloaded every version of Perl5 ever released and decompressed them.
Then, I put all the resulting .tar files in a single .tar file and tried to compress it using various compressors:
Finally, wall clock time decompression times (WD Blue HDD):
Then, I used lrzip to perform long-range deduplication on the original .tar file:
Finally, I compressed the resulting none.tar.lrz file using bzip3:
