The total size of all the files is 4.36 GiB - - **Non-compressible data:** A lot of barely compressible files, in thes case jpeg images. The total size of all the files is 0.62 GiB - - **A lot of many small text files:** A lot of small text files, all the files are under 1MB in size. The total size of all the files is 0.96 GiB - - **A few text files:** A few text files. The total size of all the files is 9.54 MiB - - **A few mixed files:** A few files varying in size and type. The total size of all the files is 6.66 MiB - -The algorithms tested were the following: - - XZ - - LZMA - - PGZIP (parallel gzip) - - PBZIP2 (parallel bzip2) - - LZ4 - - PLZIP (parallel lzip) - - ZSTD - - RAR - - 7ZIP - - ZIP - -The tests were run on a system with the following specs - - Ryzen 9 3900X CPU - - 32 GB DDR4 2133 MT/s memory - - nvme gen4 ssd - - Arch linux kernel version 6.12.8 - - xfs file system - -Notes: All the algorithms were run with the maximum compression mode. - -## Results - -All the tables have the next categories: - - **Time:** Seconds. The time the compression process took. Lower is better. - - **Compession:** The compression rate after the process. Higher is better. - - **Time normalized compression:** The compression normalized to the time obtained ny dividing the compression by the time. Higher is better. - ### Non compressible data Test with "Non compressible data" sorted by "Time" -| Compression Algorithm | Time | Compression | Time normalized compression | -| :--------------------
