Greeting,
FYI, we noticed a -22.7% regression of will-it-scale.per_process_ops due to
commit:
commit: bd0b230fe14554bfffbae54e19038716f96f5a41 ("mm/memcg: unify swap and memsw
page counters")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
I really fail to see how this can be anything else than a data structure
layout change. There is one counter less.
btw. are cgroups configured at all? What would be the configuration?
Hi Michal,
We used the default configure of cgroups, not sure what configuration
you want,
could you give me more details? and here is the cgroup info of
will-it-scale process:
$ cat /proc/3042/cgroup
12:hugetlb:/
11:memory:/system.slice/lkp-bootstrap.service
10:devices:/system.slice/lkp-bootstrap.service
9:cpuset:/
8:perf_event:/
7:rdma:/
6:freezer:/
5:pids:/system.slice/lkp-bootstrap.service
4:net_cls,net_prio:/
3:blkio:/
2:cpu,cpuacct:/
1:name=systemd:/system.slice/lkp-bootstrap.service
Best Regards,
