Hey Guys,

I got a kind of strange Question:

We got some Hypervisors connected to an x86 Storage ( NFS )

The Machines are connected via 10 Gbit with that Storage. When I try to rsy=
nc some Files we reach almost the Maximum Bandwidth.

But, when I copy some VM=B4s, Templates or do something Stroage related in =
Ovirt I just can reach 1000 M/bit.

Is there any kind of "Config Limitation"?

My biggest Problem:

We work a lot with Templates. When I deploy 10 VM=B4s based on one Template=
 the VM=B4s are getting very slow and the Storage seems to be the Problem

Thanks a lot
