Idle curiousity about memory usage
1. The problem statement, all variables and given/known data:

So... I'm going to try to fit this into the template but it'll be a little weird, since this is more of a random question on my part than a homework question, but I thought I had better include it here since it's directly relevant to my homework.

I was just wondering what you can tell from the memory usage. We had a final project to do that involved running a program on the school server. I ran top and noticed that my group's memory usage was around 6.3% and the other group's was only 0.7%. I'm assuming this means we wrote a clunkier program, but since I'm coming from a linguistics background and not Comp Sci I don't really trust my instincts on this.

2. Relevant commands, code, scripts, algorithms:

I used top.... I guess I don't really have any other relevant info for this section.

3. The attempts at a solution (include all code and scripts):

I googled memory usage, haha. So far, I've found out a lot of really interesting information, but nothing that tells me if this means I wrote an inefficient program.

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

San Jose State University, San Jose, CA, USA.
Prof - Hahn Koo
course - ling 165 LING165

wincache_fcache_meminfo

WINCACHE_FCACHE_MEMINFO(3)						 1						WINCACHE_FCACHE_MEMINFO(3)

wincache_fcache_meminfo - Retrieves information about file cache memory usage

SYNOPSIS

       array wincache_fcache_meminfo (void  )

DESCRIPTION

	Retrieves information about memory usage by file cache.

RETURN VALUES

	Array of meta data about file 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 file cache

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

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

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

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

EXAMPLES

       Example #1

	      A wincache_fcache_meminfo(3) example

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

	      The above example will output:

	      Array
	      (
		  [memory_total] => 134217728
		  [memory_free] => 131339120
		  [num_used_blks] => 361
		  [num_free_blks] => 3
		  [memory_overhead] => 5856
