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?
