Hello,
I'm studying Darwin kernel and I found some information about
working set on Mach Virtual Memory.
"The first time that an application is launched in a given user
context, the initial working set required to start the application is
captured and stored in a file..... /var/vm/app_profile".
Why I didn't find this file into my iMac with OS X 10.1.5?

In Mac OS X 10.1.x (Darwin 5), the VM system would dynamically track working sets of running applications and use that for page replacement/fetch purposes. But the cache of early working set info across launches is new to Mac OS X 10.2 (Darwin 6).
