RSIZE and VSIZE
Authored by: Halo1 on Nov 09, '02 12:29:02PM

FWIW, VSIZE does not necessarily cost you swap space. In previous version of Mac OS X, e.g. the VSIZE of classic was always 1 GB. This didn't mean that it allocated one gig of swap space however, simply that it's virtual address space was 1 GB large.

Most of the time the VSIZE indicates the amount of memory that the application and its library occupy and allocated. However, if you allocate memory without using it, it doesn't cost you anything (no swap is created for it or so).
