If your swap drive is empty, as yours is, there is no shortage of ram. 
If your ram is full, as yours is, simply think of this as an automatic 
ram drive created and maintained by the system. You should be worried if 
ram is not full, unless your ram is greater than the total of everything 
accessed in the recent past.

Basically, seeing your report is verification of 'perfection' with 
regards to efficiency (although I suppose the algorithm for what is 
stored could be argued until the end of days). Use of ram is fast... 
swap slow. Think windows rolling off to swap for a moment.
