Compression test
I made some test on multiple of the compression algorithms and tools found on linux.
Test setup
The algorithms were tested on the following situations:
- Lots of data with mixed types and sizes: A lot of various types of files of varying sizes. 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.
