<br>
<b>Problem:</b> The virtio network device operates on 100Mbits. <br>
<br>
How do I know that it operates on 100Mbits ? <br>
I copy a single big file via rsh and I can see the real speed. The 
network is completely dedicated to this operations, that is, there is no
 other traffic between other machines.<br>
<br>
<b>Question:</b> What do I have to do to use full bandwidth ?<br>
<br>If this is not the best forum to ask this question, do you suggest another channel ?<br><br>
Thanks in advance,<br>
