Thank you for collecting data on this. Were you able to find any
regression when compared to no memory accounting at all?

It looks like you agree with the approach and the results. Did you find
any other issues with the patch?

I am also including Robert in this thread. He had some concerns the
last time around due to a small regression on POWER.

Regards,
    Jeff Davis
