The kernel’s CFS bandwidth controller is an effective way of controlling
just how much CPU time is available to each control group. It can keep
processes from consuming too much CPU time and ensure that adequate time is
available for all processes that need it. That said, it’s not entirely
surprising that
the bandwidth controller is not perfect for every workload out there. This
patch set from Huaixin Chang aims to make it work better for bursty,
latency-sensitive workloads.
