February 17, 2010 Window 7 computers consume nearly all RAM; less than half of the XP PCs do, which results in performance bottlenecks. According to data from "Devil Mountain Software" Craig Barth- Chief Technical Officer. 86% of the Windows 7 computers in his XP Net Pool are regularly consuming 90%- 95% of their available RAM. Which results in slowdowns as the systems turn to disk based virtual memory to handle tasks. The low memory condition of most Windows 7 PCs is even more notable considering the amount of RAM. An average 3.3 GB of memory as compared to XPs 1.7 GB and Windows Vista 2.7 GBs. XP Net's data couldn't determine whether the memory usage was by the Windows 7 Operating System itself or an increased amount of applications. But they are working on finding the dominant factor in the increased memory use.
