820 use 1690m (mega) in virtual allocation and 276m in residual or
resident memory
smbd use 12612 ko in virtual allocation and 4952 ko in residual or
resident memory
extract of man top :
o: VIRT -- Virtual Image (kb)
The total amount of virtual memory used by the task. It
includes
all code, data and shared libraries plus pages that have
been
swapped out. (Note: you can define the STATSIZE=1 environment
vari-
able and the VIRT will be calculated from the /proc/#/state
VmSize
field.)
VIRT = SWAP + RES.
p: SWAP -- Swapped size (kb)
The swapped out portion of a taskâs total virtual memory image.
q: RES -- Resident size (kb)
The non-swapped physical memory a task has used.
RES = CODE + DATA.
