The xz command is a very powerful program for compressing files.

* Average compression ratio of LZMA is about 30% better than that of
gzip, and 15% better than that of bzip2.

* Decompression speed is only little slower than that of gzip, being
two to five times faster than bzip2.

* In fast mode, compresses faster than bzip2 with a comparable
compression ratio.

* Achieving the best compression ratios takes four to even twelve
times longer than with bzip2. However. this doesn't affect
decompressing speed.

* Very similar command line interface to what gzip and bzip2 have.

A YAML parser and emitter in C++ matching the YAML 1.2 spec.

Zstd, short for Zstandard, is a lossless compression algorithm. Speed
vs. compression trade-off is configurable in small increments.
Decompression speed is preserved and remains roughly the same at all
settings, a property shared by most LZ compression algorithms, such
as zlib or lzma.

At roughly the same ratio, zstd (v1.4.0) achieves ~870%% faster
compression than gzip. For roughly the same time, zstd achives a
~12%% better ratio than gzip. LZMA outperforms zstd by ~10%% faster
compression for same ratio, or ~1–4%% size reduction for same time.
