Client extremely slow on M1 Mac

[TheCleric]

I have the following setup:

• M1 Macbook Pro (Client – Hardwired network – Sequoia 15.3.1 – NoMachine 8.16.1 free)
• Intel Macbook Pro (Client – Wireless network – Sequoia 15.3.1 – NoMachine 8.16.1 free)
• Debian (Server – Hardwired network – Debian 12.9 KDE Plasma – NoMachine 8.16.1 free)
• Debian 2 (Server – Hardwired network – Debian 12.9 KDE Plasma – NoMachine 8.16.1 free)

When connecting to the servers from my Intel Macbook everything works great. When connecting from the M1 Macbook the screen update and input lags significantly. Mouse clicks and keypresses seem to take 3-5 seconds to register. To eliminate differences I’ve also tried connecting over wireless from the M1 (like I do with the Intel Mac) and noticed no difference.

To try to alleviate this I’ve turned down the display settings on the M1 client to:

• Lowered slider on Display Quality to Best Speed
• Disable multi-pass display encoding
• Disable client side image post-processing

However none of this seems to have made a difference. Any ideas/help?

We’re not aware of any slowness on client side. What you can do is this:

– Launch Activity Monitor
– While the client is slow to update, do you see a NoMachine process with high %CPU values? What is the spike value?
– Select the NoMachine process with higher %CPU, and in the top Activity Monitor menu click the down arrow and select “Sample Process” in the popup
– Click “Save…” in the opening window to store the file. Zip up and send it to us by attaching here or directly to forum[at]nomachine[dot]com.
