In prstat the SIZE and RSS columns tell you how much memory a process consumes.
SIZE is wrongly described as SWAP in the man pages, but it's about the same: virtual memory including reservations.

Code:

man prstat
...
     SWAP

         The sum of swap reservations of the associated processes
         for  each  user,  project,  task,  or  zone. This counts
         shared memory only once for each user, project, task, or
         zone.   Swap  is reserved when anonymous memory is allo-
         cated or files are mapped private. The value of swap  is
         expressed  in kilobytes (K), megabytes (M), or gigabytes
         (G).

     RSS

         The resident set size of the process (RSS), in kilobytes
         (K),  megabytes  (M), or gigabytes (G). The RSS value is
         an estimate provided by proc(4) that might underestimate
         the actual resident set size. Users who want to get more
         accurate usage information for capacity planning  should
         use the -x option to pmap(1) instead.

"resident" means: resident in RAM.

wincache_ucache_meminfo

WINCACHE_UCACHE_MEMINFO(3)						 1						WINCACHE_UCACHE_MEMINFO(3)

wincache_ucache_meminfo - Retrieves information about user cache memory usage

SYNOPSIS

       array wincache_ucache_meminfo (void  )

DESCRIPTION

	Retrieves information about memory usage by user cache.

RETURN VALUES

	Array of meta data about user cache memory usage or FALSE on failure

	The array returned by this function contains the following elements:

	      o memory_total - amount of memory in bytes allocated for the user cache

	      o memory_free - amount of free memory in bytes available for the user cache

	      o num_used_blks - number of memory blocks used by the user cache

	      o num_free_blks - number of free memory blocks available for the user cache

	      o memory_overhead - amount of memory in bytes used for the user cache internal structures

EXAMPLES

       Example #1

	      A wincache_ucache_meminfo(3) example

	      <pre>
	      <?php
	      print_r(wincache_ucache_meminfo());
	      ?>
	      </pre>

	      The above example will output:

	      Array
	      (
		  [memory_total] => 5242880
		  [memory_free] => 5215056
		  [num_used_blks] => 6
		  [num_free_blks] => 3
		  [memory_overhead] => 176
	      )
