    By great work from Squuiid, https://forums.macrumors.com/thread...nics-to-use-small-tree-macos-drivers.1968456/ Thanks him so much!!!!

    I successfully installed a X540-T1 with Akitio Thunderbolt 2 box on my latest Mac Pro(Trash can).

    Then I tried to test the throughput with my Synology 1817+ with a Synology 10GE card installed. I found a very wired situation, I need your guys' help, and instructions.

    192.168.0.2 is the address for my Synology server, and I use iperf3 in both side to test the through put.

    When Sinology as server, and Mac Pro as client, I got:
    Connecting to host 192.168.0.2, port 5201
    [ 5] local 192.168.0.21 port 49835 connected to 192.168.0.2 port 5201

    Then when I do it vice verse, I got:

    How can the speed diff so much?? more than 10 times. anything I made wrongly?

    When I tried the smb file copy, the file transfer speed relect the same big difference on thoughtput.

    Btw, I disabled smb signing on mac.

    Thanks in advance!

    This could literally due to anything, need more info about system resource usage, clients and network config...

    Thank you LK!

    I just tried the iperf3 with other two machine with 10GE as well, both are Windows, one is win10, and another one is Win server 2016, both show the similar results, so the problem can be narrow down to the mac pro.

    My configuration on Mac Pro is:
    1. Mac Pro late 2012, with 32G RAM
    2. Akitio thunderbolt 2 to PCIe box
    3. Intel X540-Ti 10GE network adaptor (intel original)
    4. Installed SmallTree driver version 3.3.15
    5. Disabled smb signing
    6. MTU set to 1500

    Thanks.

    I'm more interested in the NAS config, also send some system usage stats when you're doing the iPerf with the NAS as the server.

    @qiangge Is the 10GbE card the only link to the network? If not, does it have the highest priority (is it at the top of the list of network interfaces in System Preferences)?

    While we're at it, what the situation on the NAS? Multiple ethernet connections?

    Also what drives do you have installed and in what config?

    Hi Kris,

    On Mac Pro, the 10GE is the only connection, on NAS, the 10GE is also the only connection. so I think priority is not an issue. I suspect now the problem is on the supermicro soft routing board, I have purchased a 10GE switch to test it. will arrive tonight.

    - What is the block size?
    - Can you check the internal read speed?
    - Try reading from the nas with Black Magic speed test?
    - Try iPerf from a different device on your network?
    - During iPerf what is the CPU and RAM usage looking like on the NAS?
