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

Hi Todd,


Yes, I’m using bridged networking. I don’t have any script that automates this testing and also I didn’t use any option in netperf.

I just did netperf with target machine name. Say netperf –H <targetmachine IP>.


As already said, I using XEN 3.0.3, which is a stable version with networking support.


You have any thought on why the throughput is asymmetry between dom0 and domU? Any thought is much appreciated.


Thanks in advance,

Hi Suresh,

Did you use bridged networking for your test?

It would also be nice to see the same test run using the route and NAT scripts for comparison.

Could you also take the iperf tests? since they are also easy to run while you have them setup.

Do you have any scripts that automate this testing?

Please also include any options that you pass to your tests.

Would you be able to run the same set of tests on any other (newer) versions of Xen?
For example, are you able to run the latest stable/unstable and/or the pv_ops dom0/domU kernels
on a recent xen version?
