    Default Are Realtek NICs the problem

    Good day everyone. This is my first post to the forum - a great resource.

    I have been running Untangle Home since June of this year. I have it installed on a dedicated Zotac CI323 box and so far have had no issues, although I'm still learning and playing with different Apps and features. A week ago I upgraded my Internet service from 200Mbs download and 10Mbs upload to 1Gbs download and 35Mbs upload. I am using a Motorola MB8600 modem which is connected directly into one of the Enet ports of the CI323 the other port (internal) is connected to a switch and my home LAN. I am running version 13.1.

    I was excited to give my new setup a speed test but the results were disappointing . From any device the best download speed I can get is around 350Mbs (upload is fine and comes in around 40Mbs). I have tried turning off the Untangle Apps one by one until there are none running but the results are the same. I have plugged a laptop directly into the internal Enet port of the CI323, again with no improvement . However, if I plug the laptop directly into the Motorola modem I can get download speeds of close to 900Mbs.

    I have read on this forum and others that Realtek NICs are an issue but would they account for this much of a drop in throughput? The laptop I used has an Intel NIC and was running Windows 7.

    I also tried running a speed test from the browser on the Untangle box and did see a slight improvement up to about 420Mbs.

    Does anyone have any ideas on improving the throughput with this box?

    Thanks in advance
    Mike

    1gbps on Realtek nics? no way. You need Intel nics and a better CPU.

    I would say your issues are a combination of NIC and PCI bus limitations.

    realtek are fine in all of our testing.

    Probably a bus limitation.
    You can try bypassing everything so it doesn't have to process at layer 7.

    I tried that and got a bump of around 100MBs still far short of my 1Gb -

    Guess I will have to save my pennies for a new PC.

    What NUC/Mini PC devices are people using that will provide me with this support. The number of devices that would be using the network would probably max out around 6.

    If you want a mini PC you aren't getting gigabit. Even in the appliance space there are only a few that can pull that off, and they are all all larger units.

    Thanks for the feedback Rob.
    So are you saying that the QOTOM i5 that is being discussed elsewhere in this forum won't cut it?

    It has the specs for it, but I'm worried about the PCI bus. We won't know until someone trys it.

    There are multiple people using the J1900 version of the QOTOM on 1Gb FTTH connections, and getting 900+ Mb. Obviously that is highly influenced by what scanning being done versus what is bypassed.

    I have the i5 version, but only a 300/20 outbound connection so can't test directly. But if I don't bypass internal VLAN traffic I can still get 900+Mb VLAN to VLAN fully inspected. So I wouldn't be too concerned.
