What happened
bzip3 is an open-source compression tool claiming higher ratios and better performance than bzip2, using a fast Burrows-Wheeler transform and context mixing. In a benchmark compressing all Perl 5 source tarballs, bzip3 finished in 7 minutes using 12GB of RAM, compared to bzip2's 17 minutes using 8MB, and outpaced xz's 12 minutes while using slightly less memory.
Why it matters
Developers and database engineers handling large text or code archives can evaluate bzip3 as a faster alternative to bzip2 and xz, but must account for its high memory footprint (12GB in this test) compared to bzip2's 8MB.
Discussion angle
Compare the trade-offs between bzip3's speed and its massive memory usage versus traditional tools like bzip2 or zstd for archiving large text datasets.
