I hope you use virtio drivers, for storage and for
network, inside your VM ?</blockquote>

<div>NOPE! i am not using virtio neither disk nor in
Ethernet. is it important to use virtio when using storage
box? because i have never used External boxesbefore i only
used local storage with RAID1 (mdadm) and used same old
RAW and QCOW images. and they were perfectly fine for me.<br>

It's not because you use an external storage, but différences can be
more visible, because external storage is often slower than local
storage, at least for latency.<br>

I always try to use virtio drivers, as in theory, they must be
better, lower latency and better throughput.<br>
But you must test, it can depend on the version and your OS.<br>
<br>
After testing local disk I/O in your VM, to test Windows
driver/KVM/NFS storage, you could test network without disk I/O,
using iperf between your VM and your samba box.<br>
I think you can find iperf for Windows. Here for example :
