    Hi everyone,

    I have a cloud computer in Ubuntu with good specs and I connect to this cloud computer with my raspberry pi zero 2 (only 512m ram) as a thin client.

    I can successfully connect using NoMachine, and the performance is acceptable for normal usage (eg. browsing web, coding)
    I never use it for playing games, or watching videos, so I feel good with it.

    So my question is that, how to make it even faster.
    The main bottleneck should be the hardware of pi zero 2.

    What should I set in the NoMachine setting on the server and client?
    I noticed on server, there are 5 settings in the ‘performance’ section:
    1. ‘Use a specific display encoding’
    2. Use hardware encoding
    3. Use a specific frame rate
    4. Use acceleration for display processing
    5. Use X11 vector graphics mode in virtual sessions
    (2,4,5 are turned on currently)

    For client side in the display section:
    1. Disable network-adaptive display quality
    2. Disable multi-pass display encoding
    3. Disable frame buffering on decoding
    4. Disable client side image post-processing
    5. Request a specific frame rate 30FPS
    (4,5 are turned on currently)

    Just want to know whether my setting is correct. (for a high specs host , low specs client and normal network)
    thanks for help

    Hi,

    in your case I would not change any of the default settings and let NoMachine adapt automatically to network conditions and available hardware resources, but with one exception: check the ‘Disable client side image post-processing’ option, that can be a heavy operation for your pi. Do not choose a specific codec or a specific frame rate, as NoMachine will use, at any moment, the best values to optimize performance.
