Over 90% of Windows 7 PCs max out on memory

Not much better than Vista says researcher

Article comments

If Windows 7 users are having performance problems, it could be that the operating system is maxing out their PCs' memory according to a researcher. In fact, nearly nine out of ten machines are consuming more than 90 percent of their RAM claimed an executive from Devil Mountain Software.

Citing data from the company's community-based Exo.performance.network (XPnet), Craig Barth, Devil Mountain's chief technology officer, said that new metrics revealed an unsettling trend. On average, 86 percent of Windows 7 machines in the XPnet pool are regularly consuming 90 to 95 percent 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 percent 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 percent 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."

The low-memory condition of most Windows 7 PCs is even more notable considering the amount of RAM in Windows 7 systems: According to XPnet's polling, Windows 7 PCs sport an average of 3.3GB of memory, compared to 1.7GB in the average Windows XP computer. (Machines running Windows Vista contain an average of 2.7GB.)

"Windows 7 machines have almost twice as much memory to work with," said Barth, "but the numbers show just how much larger and more complex Windows 7 is than XP."

Barth acknowledged that XPnet's data couldn't determine whether the memory usage was by the operating system itself, or an increased number of applications, but said that Devil Mountain would start working on finding which is the dominant factor in increased memory use.

Other data that Devil Mountain collates as part of a new metric dubbed "Windows Composite Performance Index" (WCPI) quantifies peak processor workload and I/O performance. Both of those measurements are also higher for Windows 7 systems than for XP machines. While 85 percent of the former are running at peak I/O loads, only 36 percent of the latter do; the numbers for CPU workload are closer, as 44 percent of Windows 7 computers are running a computational backlog that delays processing tasks, compared to 36 percent of the XP systems.

"This is alarming," Barth said of Windows 7 machines' resource consumption. "For the OS to be pushing the hardware limits this quickly is amazing. Windows 7 is not the lean, mean version of Vista that you may think it is."

Long-time computer users are more familiar with the opposite: that hardware stays ahead of operating system requirements. "On current-generation hardware right out of the gate, Windows 7 is maxing out the resources. The old trend just isn't the case anymore. Now, everything that Intel giveth, Microsoft taketh away," Barth said.

"I think this is something that everyone in their gut knew, but now we have data," said Barth. "The metrics don't lie."

Users who want to compare their computers to the current WCPI numbers can do so by registering with XPnet and then installing the DMS Clarity Tracker Agent from Devil Mountain's site.

Tom Jaworski said: Do they take note of how much RAM these computers have You cant compare a computer that has 512MB of RAM to one that has 4GB That is just absolutely ridiculous Obviously its going to max out on PCs that have a small amount of RAM at their disposal I had 4GB of RAM and have never seen Win7 go over 2GB except when Im playing games For development purposes this has never been a problem for me I think this post is just a matter of reporting what everyone else on the internet is saying

Alexandru Lazar said: You or XPnet have to be kidding me Have you ever heard of caching

cr3 said: RAM is useless when its not being used Its caching things This is a sign of efficient memory management Judge an OS on the amount it has to resort to swapping - thatd be a truer sign of the resources being exhaustedCrappy journalism
