Re: Getting total memory used by processes

[Brett <brettspamacct@fastclick.com>]

Sorry, I tried to be sneaky but you caught me! :D I should have said 
that I'm seeing the same thing with both the -rmap and stock kernel, the 
data I collected was from a stock kernel.

Here's the data from an 2.4.22 -rmap kernel:

# getmem.pl
Total size = 4967032

# cat /proc/meminfo
         total:    used:    free:  shared: buffers:  cached:
Mem:  1056083968 1047187456  8896512        0 12722176 592035840
