ntpd high cpu usage

[itn3rd77]

Hi everyone,

I figured out that my ntpd process is always the second top process behind suricata regarding cpu usage.
Suricata is mostly around 25% followed by ntpd with around 10-12%, followed by ntopng.

Is this a normal figure for ntpd? It feels a lot to high from my prespective but I lack any comparisons.
The logfile is fine. No errors and and even on debug not much is shown. Any ideas what is causing ntpd to use so much cpu?

My CPU is a i5-7200U CPU @ 2.50GHz (2 cores, 4 threads).

Thanks and best regards
Ingo
