[CLUE-Tech] top and system load

[Jason Friedman]

I've printed below the output from the top command:

   2:25am  up 27 days, 13:12,  7 users,  load average: 2.00, 2.00, 2.00
93 processes: 85 sleeping, 7 running, 0 zombie, 1 stopped
CPU states: 42.8% user, 57.1% system,  0.0% nice,  0.0% idle
Mem:   383960K av,  380748K used,    3212K free,    1756K shrd,   
15532K buff
Swap:  265032K av,      20K used,  265012K free                  
208416K cached

I'm not familiar with the meaning of these numbers.  Is my system being 
barely touched, overwhelmed, or something in the middle?
