As Michal said, is a backend problem, since from when we started using
RHEV-m we had slowness issues and its because the "joint venture"
Windows (Powershell) and Java does not always work as expected and
always take alot to collect those kind of informations (forgetting
about Java Exception and/or Powershell issues). We hope that in RHEV-m
3.0 we does not have those issues anymore since its powershell free.
