Let's say that if the original poster didn't see the difference (a) he has
NO functioning "perceptual hardware," or (b) he hasn't tried it, which I
invited him to do.

I was making the point that no quantification is needed, rmap is at the
"wow that's better!" level overywhere I've tried it.

Now if someone could get the rmap performance with memory pressure, add
the -aa improvements to heavy i/o and large memory, and season with a
touch of J4 scheduler, I think we could have response which would blow
your fingers off the keyboard.

OT: has someone gotten 2.4.17 rmap-11c and J4 playing together? I looked
at it for about five minutes but had no time last night.
