Hi Z!
I like the idea from TJ Edmister with the background change as
easy to implement and easy to eyeball visual feedback of load,
but let me tell you an anecdote: Once I upgraded from a 386 to
a 6x86 CPU, but had no new VGA card yet. I played with an old
Mandelbrot set program and was surprised

You know: graphics is one thing - this is just actual "fun project" -
but being able to detect instantly the weak place in program, which is
causing unnecessarily high CPU load (say: looping for a key without
any "pause 10 ms"), is the other useful thing. Then actually I'm
looking for something of

For total runtime, you could do RUNTIME YOURPROGRAM at the prompt...

You do not have to explicitly program anything for this:
Just run FDAPM APMDOS at some time, e.g. in your autoexe

Actually you can use FDAPM for that: While the APMDOS
function is active, FDAP
