Nxnode.bin using 5% CPU when no client connected

[cdmackay]

hi all,

I’m evaluating the Linux free desktop product before purchasing.

I wasn’t surprised to see considerable NX cpu usage whilst a client was connected, but I was surprised to find that nxnode.bin seems to use a constant 5% cpu when there are no clients connected

I’m using the inbuilt X server, with an XFCE desktop. It stops when I logout before disconnecting a client, thus stopping the inbuilt X server.

This is on Debian, on an older system, 8GB RAM. Intel Core2 Duo E8400 3.00GHz

NoMachine 6.4.6-1

Is the constant 5% cpu expected, when no client connected? Any way to reduce it?

Thanks very much indeed.

Hi,

this is not expected in general, but consider that when you disconnect without logging out, desktop environement and applications continue running, doing their stuff and possibly making requests to the X server (which is built in the nxnode process in this case).

If you feel the CPU usage is not justified anyway, you can try to gather more info on what is happening with the following commands:

# strace -f -p <pid>

# top -b -n 1 -H -p <pid>

Where <pid> is the process ID of the nxnode process which is consuming CPU. You can send the outputs of those commands to forum[at]nomachine[dot]com. Please send along also server side logs gathered as explained in https://www.nomachine.com/AR10K00697.

Great, thanks very much. I will investigate.
