Anecdotally, a couple of people have said "it works" and a couple of people
have said "it makes no difference". I do believe that people doing compiles
could see a difference.
To determine if it was real, we did an experiment with memory model high and
memory model medium and measured the whiteout duration. We did not see any
statistical difference between the two. It could be that that was not a
good test, but we don't know of a better test.
If we have a better test, let's do an A/B test and find out the answer to
this puzzling question. We also know that memory model high on real world
users uses about 25% more RAM.
Another option is to be less aggressive on the memory model medium.
