I have a few Ubiquiti APs. When transferring from servers with 10gig NICs the speeds are slower than when transferring form computers with 1gig NICs (to clients).
—————————lots of details below————————
What I am seeing is that if I run a server with a 10gig nic, my wireless tranfsers are slower (capped at around 300mbps) than when I use the onboard intel 1gig nic. When using the 1gig nics my wireless transfers are at around 600mbps up and down. I saw this happen originally with an AC-Pro, and it is continuing to happen with my nanoHDs. I've ruled out pretty much everything, and it seems the only common factor is when transfering from a computer with a 10 gig nic. I will describe below all the different scenarios I tested (that I remember). I am wondering if anyone has any ideas? At this point I am thinking either some kind of offloading on the NIC is getting in the way, or some kind of flow control on the APs. Below all of the scenarios. When I say "Fast" I mean the expected 600mbps up/down; "Slow" means capped at 300mbps, though usually the from server to wireless client direction is the slowest. Also, all clients experience this MB PRO 3x3AC, iPhone 2x2AC, Dell Laptop 2x2AC.

Debian 9 (Chelsio T420) -- any swtich -- Freenas 11 (Intel X520)= Fast (9.5gigabit/s)
Note, that the Chelsio uses optical cables and the X520 uses DACs, so cables are ruled out too.
I am at a loss.
