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

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? Cheers, Todd _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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, Suresh. ________________________________ From: Todd Deshane [mailto:deshantm@gmail.com] Sent: Wednesday, June 25, 2008 10:25 AM To: Suresh Ramamurthy (WT01 - Embedded & Product Engineering) Cc: zanghongyong@ncic.ac.cn; xen-devel@lists.xensource.com Subject: Re: [Xen-devel] Reg: Throughput b/w domU & dom0 Hi Suresh, Did you use bridged networking for your test?
