I'd like confirm ecloud's idea that it is a Rock64 USB 3 problem., see
Pine Rock64 forum
or better if USB 2 and USB 3 devices are mixed, as the thread suggests.
I'm running Rock64 at the latest build:
Linux rock64 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310 #1 SMP Wed Aug 28 08:59:34 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux
and use a ZWO ASI294MC camera and a USB WiFi dongle:
Ralink Technology, Corp. RT5370 Wireless Adapter
Having the camera and the WiFi dongle plugged in both at USB 2 port, besides that the camera has longer to download, the
system works. If I plug in the camera at the USB 3 port and reboot, the wireless connection speed is never faster than 1...10 Mb/s
(should be ca. 60 Mb/s). If I do the same while the system is running I loose WiFi connection at all (see log file at the end).
A possible solution:
If I use a powered USB 3 hub and connect all devices to the hub, while no device is attached to USB 2, I can even stream
at 4x4 binning with about 2.2 fps. Even under these circumstances the INDI GUI is still responsive.
Kind regards, wildi

No NUC (Gemini Lake ASUS PN40), and a different camera (ASI1600), but maybe it gives helpful info:
Streaming (in 16bit mode) in EKOS (EKOS on Laptop, INDI on PN40, connection 1Gbit wired) runs around 6fps (5.6-6.4). If I run kstars on the PN40, too, (display via XVnc) it's down to 4.6-4.9 fps.
For comparison, ASICAP (run on PN40, display via XVnc) runs at 9-9.5 fps
So there's probably also more behind it than (just) USB bandwidth.
