Pfsense 2.2 esxi 5.5U2 vmxnet3 - slow



  • Hi

    I have two esxi5 with 10ge connectios, 2 x pfense, vmware tools (vmxnet3). When doing iperf between the two vms network is really slow 300-400Mbits/sec :(

    Any clues?

    Thanks
    Felix



  • could you try with a clean install without vmware-tools ? (to try with the builtin vmxnet3 drivers).

    most people manage to get around 1.5-2 gbit/s  pushed through when using vmxnet3 adapters  … so something is probably going wrong.
    are the cpu's maxed out when checking this from your vsphere client?
