Round‐trips scores

This page presents tables of compression/decompression round-trip scores for the Silesia tests.

The score is computed as such: score(lambda) = compTime + 2*decompTime + lambda*compSize

with lambda acting as a parameter used to mix the weights of the times and size respectively.

A lower score is better. Small lambdas favor the times while big lambdas favor the size.

The test machine is an AWS c5a8xlarge: AMD EPYC 7R32 (32 vCPUs), 64 GB RAM running Ubuntu 24.04 LTS.

Tested with Kanzi 2.3.0

lambda = 1e-8
