For large file sets, 7z provides multi-core compression, making it faster than many single-threaded alternatives. More details on using 7z with block devices ?

Scripts (e.g., PERL) can be written to customize compression levels based on file extensions.

Using algorithms like LZ4 is recommended for data that is already compressed, as it prevents inefficient re-compression and speeds up the process, achieving high compression/decompression speeds.
