[Xen-devel] Reg: Throughput b/w domU & dom0

[<ramamurthy.suresh@xxxxxxxxx>]

Note: Forgot to add the detail netperf results.

 

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 –> DomU:

 

Recv Socket Size bytes	Send Socket Size bytes	Send Message Size bytes	Elapsed Time Secs.	Throughput Mbs/sec
87380	16384	16384	10.01	231.61

 

 

2) DomU –> Dom0:

 

Recv Socket Size bytes	Send Socket Size bytes	Send Message Size bytes	Elapsed Time Secs.	Throughput Mbs/sec
87380	16384	16384	10.01	409.11

 

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.
