Hi all,
 
I used netperf to measure throughput between dom0 & domU. 
 
The throughput between dom0 -> domU was 256.00 Mb/sec
                                    domU -> dom0 was 401.15 Mb/sec.
 
1) Dom0 ?C> DomU:
 
Recv 
Socket

Time
Secs.Throughput
Mbs/sec
87380 16384 16384 10.01231.61

 
 
2) DomU ?C> Dom0:
 
Recv

The throughput between dom0 & domU seems to be very asymmetry. To my surprise 
the throughput between domU -> dom0 is more. The value which I specified are 
consistent values. Is there any reason for throughput being more between domU 
-> dom0? Please share if you have any information regarding this.
 
Thanks in advance,
Suresh.
