    If I can be forgiven for posting another forum link here, this is a great example of the difference between hardware offloaded routing and a software stack.

    Ubiquiti/Unifi is doing a bit of playing around with IDS and what they call "smart queues", which is software QoS. My own testing is pretty close to the post from this guy:

    https://community.ubnt.com/t5/UniFi-...ht/true#M14488

    Note that the degradation is far worse than he thinks. That router he's using is a Cavium CN5020 single core MIPS proc @500Mhz, but with a neat packet processing hardware offload. Much like other inexpensive but built-to-route hardware, it will actually route at gigabit (unlike his top end 100Mbps testing). But as soon as he throws up the ids/qos, putting the routing load purely in software on that VyOS-based system, the performance drops to 25-60Mbps. (My own testing had this particular piece of hardware topping out at ~30Mbps with the same.)

    Anyway, all kind of academic discussion from here, as Untangle already necessitates the more involved software packet processing. But this gives a good example of how on the *same* hardware that is capable of pushing Gbps speeds, enabling of certain software processing can absolutely change the performance.

    Yes, and that's also why I only use appliances now, instead of custom build PCs. You need a mainboard that's designed for a network role, that's precisely how you're able to get that much performance out of the u25.

    You've actually got offloading in those NICs. You've got the PCI lanes to saturate them. You simply don't get these features on a desktop board, and on most of the small form platforms you see on the shelf today.

    If you want gig with your own build you should go min I3 Kaby lake, I got gig with I3 7100

    Ugh... Supermicro...

    NEVER AGAIN.

    Seriously, everyone use that junk at your own risk. Having to all but return over 30 systems because they hated a specific Linux kernel was really bad, only for Untangle to update and have them all magically start working again?

    Yeah... no... never again.

    Lol on that one Sky... There are many tens of thousands of Supermicro servers running perfectly fine in industry. I'll stick to Supermicro, as I have for 15 years, thank you.

    Sorry YOU had problems with it in a very specific configuration/OS/setup, but they work fine for almost all - that is why they are the largest 3rd party motherboard manufacturer in the server space by a huge margin.

    *I* had issues with about six different motherboards over an 8 year window. So please, keep supporting that useless company. For the rest of us with brains, we'll go elsewhere to places that know what support and proper life cycles are.

    The specific incident I mentioned was only the first, of a long line of problems. Almost bankrupted me...

    They hold their position in the market by taking zero responsibility for anything short of utter failure.

    And of course as I say that there's a dual opteron 2u Supermicro behind me that's been running great for 10 long years. I finally pulled her out of service this year. They do make good stuff, they just don't support it well enough. Well... unless you're in their little channel system with volume, in which case they jump through flaming hoops. But I'm small fish, they don't care.

    They gave me a brand new server after having mine for 2.5 years with the Atom killing bug. Mine was still running without issue.

    All I did was show them a couple of links like this from Ars and the like and they gave me a new one.

    I went with an i3-4370 (3.8ghz). So the clockspeed really pushes it quickly. Speedtests are 950ish both ways. Real world data I've not found anything able to push more than 50MB/s. Next upgrade will put in an i5 or so.

    You don't need to add more CPU, that i3 will handle anything you're ever going to throw at it. Even a multicore Celeron would have been sufficient, so long as it wasn't one of the renamed Atoms. 950mbit is wirespeed, you're in a place where the actual gigabit cable cannot go any faster because you never get 100% of wire, the best you can reasonably hope for is 80% of wire. And you're well above that!
