3doubled Posted April 10, 2019 Share Posted April 10, 2019 Hi, While trying to diagnose performance issues related to my NextCloud docker I came across a weird CPU utilization pattern. The image below was taken with all dockers stopped except Netdata: Every couple of seconds, one core is utilized 100%. How can I identify exactly what process is doing this? Unfortunately, Netdata just labels this process as "other". Thanks PS. Here is my post regarding my NextCloud performance issue, although I don't think it seems to be related to this weird CPU behavior. tower-syslog-20190410-0059.zip Quote Link to comment

Now that I know what is causing it I see there are other threads about this here: This thread in particular people recommend either disabling cache dirs or at least excluding shares with complex folder structures, such as \appdata. I'm going to give the latter a try first, but disabling it might not be a bad idea, I don't spin my disks down ever, so cache directors is probably not doing much anyway. [EDIT] Excluding \appdata seems to have done the trick. I also set the max folder depth to 8 instead of unlimited. The CPU utilization spikes are gone entirely.
