Firefox uses mmap to map certain files into memory. This memory is
then accessed somehow which results in pageins and pageouts. I would
like to time the pageins and pageouts and total these up per mmap-ed
file.
How can this be done on Leopard?
I see the vminfo provider with a bunch of probes (below) but how do I
use it?
Thanks, Joel
