What is the new compression utility that offers high compression ratios?

The utility that offers high compression ratios is xz. XZ is known for its exceptional performance in compressing files to a smaller size compared to other traditional compression utilities. It utilizes the LZMA (Lempel-Ziv-Markov chain algorithm) and LZMA2 algorithms, which provide better compression rates than gzip and bzip2, especially for larger files or when high compression efficiency is desired.

In addition to its high compression ratios, xz also allows for different levels of compression. Users can choose a trade-off between processing time and size reduction, making it a flexible option for various compression needs.

Other utilities like gzip, bzip2, and zip have their own use cases and advantages but generally do not compress data as efficiently as xz. Gzip is primarily focused on speed rather than compression efficiency, bzip2 is better than gzip in terms of compression but not as effective as xz, and zip combines file archiving with compression, but typically does not achieve the high compression ratios that xz can provide.
