Test of compressing and decompressing the Linux kernel (through a different one than the compress-gzip benchmark). Interesting that none tests of different compression tools use the same metrics and workload so not easy to compare between tools.
AMD metrics show a lower on-cpu (3.63) but not single threaded and also a lot of output. Not as much branch misprediction as some other codes.

The core computation blocks show we are starting one thread per core, so relatively lower on_cpu likely indicates waiting e.g. for disk.
