Gastón Kleiman commented on MESOS-9513:
---------------------------------------
After grabbing a lot of perf traces of Mesos agents on DC/OS EE, the only
bottleneck I could find that affects vanilla Mesos is the fact that an I/O
switchboard process is launched for every DEBUG container.
If we want to improve the performance of (health) checks, we should prioritize

> Investigate command health check performance

> Key: MESOS-9513
> URL: https://issues.apache.org/jira/browse/MESOS-9513
> Project: Mesos
> Issue Type: Task
> Components: agent
> Reporter: Greg Mann
> Assignee: Gastón Kleiman
> Priority: Major
> Labels: check, foundations, health-check, mesosphere, performance
>
> Users have reported performance issues caused by too many command health
> checks performed too quickly by the default executor. Use of the agent's
> LAUNCH_NESTED_CONTAINER_SESSION call can impact the containerizer's ability
> to successfully launch containers in general.
> We need to investigate this issue and decide on a path forward to improve the
> performance of command health checks.
