"cgroup2 Resource Control strategies w/ resctl-demo"
summary
cgroup2 resource controls are shown as a working stack: resctl-demo (interactive terminal plus rdhd, rd agent) drives a synthetic memory leak and a compile side‑load to prove protection and sideloading strategies. Without controllers rps collapses to near zero in ~15–20s; with cpu.weight, memory.low and io cost/io weight enabled rps holds within the 100 ms latency target, write traffic falls from ~300 MB/s to under ~100 MB/s, and latencies stay under ~10 ms.
