Hello, Perhaps this query was answered in the past. If yes kindly point me to the same. We noticed differences in networking performance (measured via netperf over a 10G NIC) on an X86_64 server between the following two configurations : 1) Server run as a KVM Host (but with no KVM guests created on it (or) no extra bridges created other than the default vibr0 bridge) vs. 2) The same server running the same version of Linux but without any of the virtualization software installed on it. Config #2 performed much better ! Is this expected ? What are the reasons behind this ? Is there any way to gain back the loss in performance on the KVM host without having to uninstall the virtualization software (i.e. in Config 1). Thanks!
