I know that's tongue-in-cheek, but it's a bit too pessimistic.
I'm a capacity planner, and CP is done stri

I worry that we're making a silent change to "all memory is
considered used" again. If we are, we will have to kludge
up a metric, like scan rate that spiked when we run out of memory.
I used to be on the ABI (stability) team and my boss would

The more we get visit counts, residence and wait
times out of Solaris, the better! I'm particularly
