    For “each process”, how about top:

    PhysMem: 238M wired, 865M active, 549M inactive, 1652M used, 395M free.
VM: 162G vsize, 1039M framework vsize, 124775(0) pageins, 9149(0) pageouts.

PID   COMMAND      %CPU TIME     #TH  #WQ  #POR #MREG RPRVT  RSHRD  RSIZE  VPRVT  VSIZE  PGRP PPID STATE    UID
7233  top          5.7  00:00.53 1/1  0    24   33    1328K  264K   1904K  17M    2378M  7233 3766 running  0

    e.g.:

    rprvt  Resident private address space size.
rshrd  Resident shared address space size.
rsize  Resident memory size.
vsize  Total memory size.
vprvt  Private address space size.
