Doc Text:
Red Hat Enterprise Virtualization Hypervisor 6.5 added support for memory-based file systems (for the purposes of testing), which included code with O(N^2) complexity. This introduced performance issues, such as high cpu consumption by vdsm, in certain environments that utilized numerous storage domains. Now, the additional support for memory-based file systems has been disabled and does not contribute to performance problems.
