    – What is the desktop environment (GNOME, KDE…) in use on the Arch server? Could you try a different one, possibly a lightweight one like Mate or Xfce?

    i3, which is quite light already

    I don’t have other devices, so no.

    I re-tested with almost nothing running on my machine apart from Chromium with this page and nomachine linux app. A bit less laggy (slightly higher fps) but still too slow and too much input lag (>1s).

    – Would you try to turn off the graphical output of the server, as explained in https://www.nomachine.com/AR03P00973, and check performance? In this case, without an X server running, NoMachine will run its own built-in X server, so we would be able to exclude another possible source of problems.

    I exit i3 and went back into a tty. From there I made sure that the nxserver was running. But from my smartphone while I do see my laptop when I try to connect to it it tells me “Error is 113: No route to host”.

    I repeated my touch and VLC test and took the statistics. See attachment. I double checked, the “Disable frame buffering on decoding” was checked during this test, but also before during the test of my initial post. Same low fps, same big latency.

    The CPU usage with htop shows ~72 processes of nxnode.bin, with 20 with the option “-H 5”. My eight cores are working and the top nxnode process uses between 90% and 120% of CPU. Overall CPU usage is 15-30% when I stream the video to my smartphone and 10-20% when I disconnect the client. nvidia-smi reports nothing related to NoMachine/nx{something} whereas it does report being used by VLC to play the video (pretty for hardware decoding).

    Thanks for your answer and for taking a look!
