If you run 'top', the basic information would be to show per-CPU
information (press '1'). Another thing to look at: press 'H' to get
per-thread entries. Do you have many many threads each taking a small
part of a core, or a few threads taking lots of CPU time?

I believe that the PID (process/thread ID) you see in top is also the
second item in each line in the output of 'core show threads'. So this
could give you some clues regarding the CPU hogs you see in top.
