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. John Hinton -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions
