You can usually also use vmstat to get this sort of info. have a look in the manual page to see which column is which. if you are getting lots of page-in activity (processes will wait) then have a look at your process memory allocation:-
Code:
ps -el|sort -nk 10
This should list processes and sort them with the largest memory allocation at the bottom (assuming that the SZ column is column 10) and you can then investigate the source of those processes.

slabtop
SLABTOP(1) Linux User's Manual SLABTOP(1)NAME
slabtop - display kernel slab cache information in real time
SYNOPSIS
slabtop [ options ]
DESCRIPTION slabtop(1) displays detailed kernel slab cache information in real time. It displays a listing of the top caches sorted by one of the
listed sort criteria. It also displays a statistics header filled with slab layer information.
OPTIONS
Normal invocation of slabtop(1) does not require any options. The behavior, however, can be fine-tuned by specifying one or more of the
following flags:
--delay=n, -d n
Refresh the display every n seconds. By default, slabtop(1) refreshes the display every three seconds. To exit the program, hit q.
--sort=S, -s S
Sort by S, where S is one of the sort criteria.
--once, -o
Display the output once and then exit.
--version, -V
Display version information and exit.
--help Display usage information and exit.
SORT CRITERIA
The following are valid sort criteria used to sort the individual slab caches and thereby determine what are the "top" slab caches to dis-
play. The default sort criteria is to sort by the number of objects ("o").
The sort criteria can also be changed while slabtop is running by pressing the associated character.
a: sort by number of active objects
b: sort by objects per slab
c: sort by cache size
l: sort by number of slabs
v sort by number of active slabs
n: sort by name
o: sort by number of objects
p: sort by pages per slab
s: sort by object size
u: sort by cache utilization
COMMANDS slabtop(1) accepts keyboard commands from the user during use. The following are supported. In the case of letters, both cases are
accepted.
Each of the valid sort characters are also accepted, to change the sort routine. See the section SORT CRITERIA.
<SPACEBAR>
Refresh the screen.
Q Quit the program.
FILES
/proc/slabinfo -- slab information
SEE ALSO free(1), ps(1), top(1), vmstat(8)NOTES
Currently, slabtop(1) requires a 2.4 or later kernel (specifically, a version 1.1 or later /proc/slabinfo). Kernel 2.2 should be supported
in the future.
The slabtop statistic header is tracking how many bytes of slabs are being used and it not a measure of physical memory. The 'Slab' field
in the /proc/meminfo file is tracking information about used slab physical memory.
