Greetings OmnisOS community! This is my first time to ask a question on this list so here goes. I’ve deployed a zone on omnios and a KVM virtual machine within the zone. I’ve been doing some initial virtio network interface performance testing with iperf and the following are my results (default out of the box for all moving parts).
Host: OmniOS build stable: r151012 Test Interfaces: GZ Phys = igb0 KVM Vnic: kvm0 over igb0 GZ Vnic: gvm0 over igb0 Zone Vnic: zvm0 over igb0 Network addressing: All vnics are with 10.128.255.249/29 Zone Brand: Omni-ti ipkg Qemu-Kvm Guest: Centos 6.6 x86_64 iPerf Results: KVM Guest -> Global Zone = 151 Mbytes (Expected close to 1 GByte) KVM Guest -> KVM Zone = 147 Mbytes (Expected close to 1 GByte) Zone -> Global Zone = 5.0GBytes (These were expected since it was a host only VNIC network) GZ -> Zone = 4.7 Gbytes (These were expected since it was a host only VNIC network) My question is are there any tweaks that I’m missing to get the full performance potential within the guest? Why am I only seeing 147 Mbytes between KVM and the hosting zone or the global zone? I’m testing with an isolated network and vnics only, so the traffic is never leaving the physical host to go over the wire. I do have cpu capped at 16 cores and memory capped at 16GB of memory in the zone. Is there some default network capping that I’m missing? Or process throttling? MTU is 1500 across the board. I did the same test with etherstubs at first but though maybe I was having an MTU mismatch because I received the same 147 Mbyte result…however a subsequent test using just the GZ -> child zone showed 5.0GBps over the etherstub switch just like when I only used the VNIC’s over igb0. Also just for grins I tested two bare metal hosts on my physical network with iperf…one being CentOS 6.5 and the other OmniOS build r151012 and received 1.09 Gbytes over a physical switch.
