This was immediately after boot.  I used ssh to log in, then ran top  
to get a snapshot at ~60 seconds after boot.  Things like getty, zsh,  
sshd, and sendmail were running (total of 23 processes).  Admittedly,  
this is a rather lame experimental design, but it was simple to  
perform, and I wanted to know if there were huge differences in  
system memory usage, as a number of people have repeatedly implied.   
This experiment convinced me that there are not any consistently  
substantial differences in memory usage, though I fully expect there  
to be variation, depending on the application(s) being run.
