Got it. Top2 is great (now that I know what it is, and what it's for).Sorry for being short!
Life is not always easy and harmonic, but I want to help as soon as I can.
top2 is router command showing all processes sorted with highest cpu load at top.
Try! And/or follow @sppmaster advice.
I'm not sure I would call my situation a "new install of firmware" since the installation occurred over 3 days ago. Top2 would have answered my question regarding high CPU utilization (until I destroyed the evidence by doing a reboot). Next time I will know.

Thank you for your help (and your patience).
