Re: Load 0.20 on a freshly installed idle system
Date: Sat, 21 Jan 2023 00:18:52 UTC
Stavros,
Load averages by themselves mean very little.
It's not a figure of cpu usage if that's what you're worried about.
Load averages on BSD are simply processes which have wanted to run at least
once in the most recent 5-second window, with a degradation over time.[1]
Unless you're having a specific problem, I'd guess to say there is no
problem here at all.
Thanks,
Paul Procacci
