That's the headline of 'top':
Code:
Tasks:  37 total,   1 running,  36 sleeping,   0 stopped,   0 zombie
Cpu(s):   0.3% user,   0.3% system,   0.0% nice,  99.3% idle
Mem:    191440k total,   138116k used,    53324k free,     7540k buffers
Swap:  1084376k total,        0k used,  1084376k free,   106912k cached

The server behaved also dull after I terminated every process except from apache..
