&gt;  &gt; &gt; i&#39;m gettting speed ~ 110 MB/s, so this is<br>
&gt;  1Gbps speed of ethernet adapter<br>

&gt;  &gt; &gt; but with in VM created in oVirt speed is<br>

&gt;  &gt; &gt; why there is so huge difference?<br>
&gt;  &gt; &gt; how can improve VMs disks speed?<br>
&gt;  &gt; &gt;<br>
&gt;  &gt;<br>
&gt;  &gt; What are your gluster volume settings? Have you<br>
&gt;  applied the following<br>
