Hi Michael,
Thanks. Time spent at idle and full load seems reasonable.
I think the majority of usage is from /usr/sbin/smbd (Samba server). Samba can be CPU intensive, try copying a file to (or from) the server and check cpu frequency with:
Code: Select all
echo -e $(( $(cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_cur_freq) / 1000 ))
Might be an idea to check temp now and then (as above command may trigger a frequency up step) with:
You could also rerun this test for 30 minutes and see if the time spent in idle improves, after disabling one service at a time:
Disable samba:
Code: Select all
systemctl stop smbd
systemctl stop nmbd
Disable dnsmasq:
If you find our project or support useful, then we’d really appreciate it if you’d consider contributing to the project however you can. PayPal or become a DietPi patron .

Ho Fourdee,
I copied a large file (1,4GB) to the samba-server. The results of
cpu were this:
Code: Select all
root@dietpiserver:~# echo -e $(( $(cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_cur_freq) / 1000 ))
1000
root@dietpiserver:~# cpu

As you can see there were all kind of states presents. Maybe i stick with the ondemandgov and throttle all the cpus to 1400Mhz?
Thx again, Michael

Hi Michael,
Thanks, yep, I believe its just a case of background services peaking CPU load. As the XU4 runs really hot, even at low loads, I think that may be the sudden rise in temps.
The CPU time in your ps aux post seems fine, nothing out of the ordinary that would indicate a program/process constantly using CPU.
It only takes around 2 seconds to reach 90'c+ at full load on this device. Capping the frequencies is recommended, I cap mine at 1.5GHz, seems to stay under 70'c.
Another option is heatsink upgrade, or, pop it in the freezer
lol

Hi Fourdee,
thx again.
Yep, I will stay with 1,5GHz as well. Until now the device is under 60 Degress. I'm fine with that
Michael
BTW: Just sad that the XU4 is the only device with a good CPU and USB3. Maybe in th near future someone like FriendlyArm build one also with USB3 and a "better" CPU.
lol
