Well, what you've posted (free output) shows that, at the time you
grabbed those snapshots, memory was not full and swap was unused, which
raises two new questions:

- what was running on the RPi then, i.e. was it Node-Red + Chromium
  or was it something else? If something else, what was running?

- how much CPU was being used at that time?

Run TOP as normal and look at the %CPU column to see what process(es) are
eating the most CPU time. If its obvious and a fairly stable set of
figures, try to take a screen shot and post that. Otherwise, use the
command "top -bn5 >toplog.txt" to capture five snapshots in the
"toplog.txt" file and post that - it might be quite large.

Note that, with 4 CPU cores in an RPi3, by default a process that is
shown as using as 25% of CPU is actually using 100% of one of the four
cores.
