PfSense speed in vsphere network - big performance difference to debian guests



  • hello,

    i did a few speed tests within my vsphere 5.1 host. I tested with iperf on pfSense. Each scenario was tested with pfSense as iperf server and client, no difference.

    All VMs had the server hardware:
    4 CPU Cores (3,3 Ghz)
    1Gig RAM

    A : pfSense 2.1 x64 (Open-VM-Tools - VMXNET 2 NIC) <-> vSwitch <-> Debian 6 x64 (VMWare Tools - VMXNET 3 NIC) : 1.95 Gbits/sec
    B : pfSense 2.1 x64 (VMWare Tools (without daemon) - VMXNET 3 NIC) <-> vSwitch <-> Debian 6 x64 (VMWare Tools - VMXNET 3 NIC) : 2.19 Gbits/sec
    C:  Debian 6 x64 (VMWare Tools - VMXNET 3 NIC) <-> vSwitch <-> Debian 6 x64 (VMWare Tools - VMXNET 3 NIC) 21.76 Gbits/sec

    In B i cant start the vmware daemon, see this: http://forum.pfsense.org/index.php/topic,60206.0.html

    Where is the difference? I cant understand it. I love pfSense and want to use it as router for my experimental vsphere host…but this isnt good.

    Best regards

    pfSense is optimized to act as a firewall, not an endpoint. Try the test with:

    Debian –- pfSense --- Debian

    Running iperf only on the Debian hosts.
