Most Windows 7 systems consume nearly all RAM; less than half of XP PCs do
By Gregg Keizer February 17, 2010
Most Windows 7 PCs max out their memory, resulting in performance bottlenecks, a researcher said today. Citing data from Devil Mountain Software's community-based Exo.performance.network (XPnet), Craig Barth, the company's chief technology officer, said that new metrics reveal an unsettling trend. On average, 86% of Windows 7 machines in the XPnet pool are regularly consuming 90%-95% of their available RAM, resulting in slow-downs as the systems were forced to increasingly turn to disk-based virtual memory to handle tasks. The 86% mark for Windows 7 is more than twice the average number of Windows XP machines that run at the memory "saturation" point, said Barth. The most recent snapshot of XPnet's 23,000-plus PCs -- taken yesterday -- pegs only 40% of XP systems as running low on memory. "The vast majority of Windows 7 machines over the last several months are very heavily-memory saturated," said Barth today. "From a performance standpoint, that has an immediate impact on the machine."
