Clarification of cores and memory usage #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
From my initial analysis of the data set, 51.61% of the tasks have a CPU
column value of 0 -- what does this mean?  Obviously each task must use at
least some fraction of the CPU.  The same goes for memory usage.  0.94% of
all tasks have a memory column value of 0.

A clarification of this would be much appreciated.

My guess is that these are instantaneous samples, e.g. calling /proc, every 5 
minutes. 
So 0 means there really isn't anything being used?
