Description - phoronix/c-ray

This is a test of 7-Zip using p7zip with its integrated benchmark feature or upstream 7-Zip for the Windows x64 build.

The workload takes 40 seconds to walk through compressing five sample workloads. It is relatively high in both speculation and front-end and thus also a lower retiring percentage and IPC. The On_CPU of ~88% reflects multiple processes being started/stopped.
