WebBackground: Compression algorithms comparisons As part of the DIANA/HEP to improve ROOT-based analysis, we have continued work in comparing compression algorithms. For this update, we include: ZSTD: Relatively new algorithm in the LZ77 family, notable for its highly performant reference implementation and versatility. WebMay 3, 2024 · The compression performance is expressed as Compression Ratio (CR) with the size of the input (uncompressed) data followed by the size of the output (compressed) data. 3:1 would mean that the data is reduced to a third of the size of the input data. This is easy to measure by comparing the input file size to the compressed file size.
