main reason, is that the NAS is, apparently, sitting idle yet the CPU usage is at 47%.
the screenshot shows the process using the most CPU (even though it's only 4.7%), i don't usually see that process sitting using that much.
sometimes i see two of those synosci processes using the same amount of CPU.
No I can't, because what you posted indicates a 4.7% CPU utilization... which, by no standard that I'm aware of is considered "high". There will always be desktop utilization when you are using the desktop view.
so you can't answer what the process is, or why it's using 4.7% CPU, so forgive me for asking, why did you even bother posting in the thread? you could have used your time better elsewhere, please feel free to do that.
@chenks Don't know what it is doing exactly, but it could be housekeeping tasks.
There are a bunch of similar named processes that I see. Sometimes I know it's thrashing from something I've forced to happen but the process named in Resource Monitor has little to tie it to what I know is happening.
