hi, Yosry Ahmed, we shared the performance impact of this commit in https://lore.kernel.org/lkml/ZbDJsfsZt2ITyo61@xsang-OptiPlex-9020/ now we noticed the commit is merged in mainline, and we observed improvements in other performance tests such like netperf and stress-ng. the vm-scalability and will-it-scale results are also included FYI. Hello, kernel test robot noticed a 4.0% improvement of netperf.Throughput_Mbps on: commit: 9cee7e8ef3e31ca25b40ca52b8585dc6935deff2 ("mm: memcg: optimize parent iteration in memcg_rstat_updated()")
