<note

Significant Greenplum Database performance degradation has been observed
when enabling resource group-based workload management on RedHat 6.x, CentOS 6.x, and SuSE 11
systems. This issue is caused by a Linux cgroup kernel bug. This kernel bug has been fixed in
CentOS 7.x and Red Hat 7.x systems.
<p>
If you use RedHat 6 and the performance with resource
groups is acceptable for your use case, upgrade your kernel to version 2.6.32-696 or higher
to benefit from other fixes to the cgroups implementation.
</p><p>
SuSE 11 does not have a
kernel version that resolves this issue; resource groups are still considered to be an
experimental feature on this platform.

Either the resource queue or the resource group management scheme can be active in Greenplum
Database; both schemes cannot be active at the same time.
</p>
<p>
Resource queues are enabled by default when you install your Greenplum Database cluster.
