Current open source compression status quo
20.03.2017
I had to create and transfer a large tar archive across the net, which took some time and made me revisit the status quo of open source compressors afterwards. I could provide some stats, but TL;DR : pixz really shines and there's absolutely no reason not to use it. I also tested Zstandard because cutting edge and everything, but found pixz to perform much better for my workload.
