CWmike writes “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, and this comes despite more RAM being available on most Windows 7 machines. ‘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.’”

An anonymous reader writes “Way back in 1974, Dave Dennis, then aged 13, decided to try out the -ext- TUTOR command on the PLATO system at the University of Illinois, and see if he could cause all the terminals of other users to go offline. It worked. And he never got caught. Of course, the powers that be eventually caught on and fixed the -ext- command so terminals by default didn’t automatically receive -ext-’s sent from other locations.”

Theovon writes “We’ve seen a few stories recently about the new Western Digital Green drives. According to WD, their new 4096-byte sector drives are problematic for Windows XP users but not Linux or most other OSes. Linux users should not be complacent about this, because not all the Linux tools like fdisk have caught up. The result is a reduction in write throughput by a factor of 3.3 across the board (a 230% overhead) when 4096-byte clusters are misaligned to 4096-byte physical sectors by one or more 512-byte logical sectors. The author does some benchmarks to demonstrate this. Also, from the comments on the article, it appears that even parted is not ready, since by default it aligns to ‘cylinder’ boundaries, which are not physical cylinder boundaries and are multiples of 63.”

Julie188 writes with this snippet from Network World “Office 2010 is still in beta and a patch is already out. Microsoft is trying to fix a bug in the email program Outlook 2010 Beta that creates unusually large e-mail files that take up too much space. The Outlook product team has offered a bug fix for both 32-bit and 64-bit systems that fixes the problem going forward, although previous emails will remain super-sized. This could be a problem for email programs that limit message sizes, such as Gmail or BlackBerry.”

It must suck to be a Windows developer. So you already have an entire legion of misguided folk hating your work for no reason (on top of the people hating your work for legitimate reasons), and then a company comes along spreading clear misinformation about Windows’ memory usage, based on that company’s performance monitoring software. To make matters worse, when said company is called out on its errors, it decides to publish the usage information of an Ars Technica editor’s computer. As such, it is advisable to uninstall the software in question.

Via newsycombinator comes a reaction at Ars Technica to the recently reported claims of excessive memory use on machines running Windows 7. From the article: “I installed the XPnet performance monitoring tool and waited for it to upload my data to see what it might be complaining about. The cause of the problem was immediately apparent. It’s no secret that Windows 7, just like Windows Vista before it, includes aggressive disk caching. The SuperFetch technology causes Windows to preload certain data if the OS detects that it is used regularly, even if there is no specific need for it at any given moment. Though SuperFetch is a little less aggressive in Windows 7, it will still use a substantial amount of memory—but with an important proviso. The OS will only use memory for cache when there is no other demand for that memory.”
