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.

Process Tree
In the process tree one can see the patterns of running workloads and then all in parallel for each one.

^{About this graph}
Overall CPU utilization shows the processes starting and stopping.

IPC is relatively low compared with other small benchmarks.
