To be clear, by "Centos 7 installation",
I meant a PC on which Centos 7 was installed.

In any case, Centos 7 has not always been this slow.
Presumably something has changed.
I've been living with this for several months,
but not forever.
I can run compilers and stuff without an internet connection,
so I could get some work done.

To get that output, I had free running in a loop and waited for
the freeze before copy and pasting.

I wasn't surprised by the result.
Occasionally top shows kswap0 (I think) in a D state.
