I have a task that under performs. I am unable to discover what is causing it. Could this be something mesos specific? Performance difference is 1k q/s vs 20k q/s
1. If manually I run the task on the host the performance is ok > I think one could rule out network connectivity on/of the host and host issues 2. If I manually run a task in the same netns as the under performing task, the performance is ok. ip netns exec bind bash chroot 04a81d99-9b99-410d-bf83-d6d70ef2c7bb/ (changed only the config port to 54) named -u named > I think we can rule out netns issues 3. If I manually remove or change the cgroups of the mesos/marathon task, the performance is still bad echo 2932859 > /sys/fs/cgroup/memory/user.slice/tasks echo 2932859 > /sys/fs/cgroup/devices/user.slice/tasks echo 2932859 > /sys/fs/cgroup/cpu/user.slice/tasks echo 2932859 > /sys/fs/cgroup/cpuacct/user.slice/tasks echo 2932859 > /sys/fs/cgroup/pids/user.slice/tasks echo 2932859 > /sys/fs/cgroup/blkio/user.slice/tasks or echo 2932859 > /sys/fs/cgroup/memory/user.slice/tasks echo 2932859 > /sys/fs/cgroup/devices/user.slice/tasks echo 2932859 > /sys/fs/cgroup/cpu/user.slice/tasks echo 2932859 > /sys/fs/cgroup/cpuacct/user.slice/tasks echo 2932859 > /sys/fs/cgroup/pids/user.slice/tasks echo 2932859 > /sys/fs/cgroup/blkio/user.slice/tasks [@]# cat /proc/2936696/cgroup 11:hugetlb:/ 10:memory:/user.slice 9:devices:/user.slice 8:cpuacct,cpu:/user.slice 7:perf_event:/ 6:cpuset:/ 5:pids:/user.slice 4:freezer:/ 3:blkio:/user.slice 2:net_prio,net_cls:/ 1:name=systemd:/user.slice/user-0.slice/session-17385.scope [@]# cat /proc/2932859/cgroup 11:hugetlb:/ 10:memory:/user.slice 9:devices:/user.slice 8:cpuacct,cpu:/user.slice 7:perf_event:/ 6:cpuset:/ 5:pids:/user.slice 4:freezer:/ 3:blkio:/user.slice 2:net_prio,net_cls:/ 1:name=systemd:/mesos/812c481b-c0a4-444a-aafa-de98da9698e2
