Hi,
please i am starting to be a little desprite about this.

We built a brand new studio working with NDI and DANTE. I have 2x PC with 10gb lan cards, switch with 2 10gbs ports, and may 1gbs ports with poe all checked by people who knows what they do to make LAN working properly.

When i copy some files, everything is as it should be, i reach 10gbps speed etc.

When i use vmix and i want to test this LAN possibilities i can never send more like 1,5 gbps and recieve more like 2gbps. Are there some restristion by vmix about the traffic which can ndi make?

I need to have like 10-12 ndi inputs and like 8 outputs and when i reach not even those numbers, my inputs and outputs sometimes starts to lag. With 1 input being like 140 mbps and all the investments which were made here i am really not in a comfort spot to be confident using this for a production i need.

I already tested a lot of settings like disabling all other 1gb ethernets, some windows intput output limits and such things but nothing helped and those 10gb ethernets just dont seem to work well with vmix.

Any ideas?

Hi,
thank you for paying attention to my topic. Next thing i found out is that if i send output to birddog ndi studio or kiloview n20 from 10gb lan card it laggs, when i lower speed to 1 gb (speed of lan) its immediately ok.

I ll try to answer:
1)yes, i tryed to copy from 10gb port to 10gb port.

2) i tryed 2 switches already. Right now its this one https://images.mironet.cz/foto/3/91403907/1.jpg

3) my NDI sources are all going through birddog ndi studio or kiloview n20, both behaving exactly the same way. I use some outputs from vmix to 3 monitors, then i collect 4-5 cameras inside studio, one of the monitor is touch screen so i have output with drawing from this one, then i send 2 outputs from the second pc to the first one.

4) behringer x32 compact with 32 dante channel card, dante virtual card and dante controller in pc

5)i am sending 1080p25 with +-110-140 mbps

6) right now i had those 8 outputs just during test as i cant safely afford them. Each is around that 140-110 mbps

7) task manager shows very good number. Im using 32gb ram, i9-9900KS, and gtx 2060 super, so on the second tab of task manager numbers are good, on the first tab, where is network also in % the number i correct but if i turn on some other 1gb lan cardds on that pc when there is for example 900mb it shows 90% which is not logic for me.


I also tryed to use 2-3 1gb lan cards but i dont know how to set it up to be able to use 2-3 gb bandwith so there was always like 1,2 gb max during my tests.
