"Windows7 high memory usage" survey

On February 19, ComputerWorld, a well-known IT website, published an article. Craig Barth, chief technology officer of Devil Mountain, a PC performance testing software company, pointed out that according to the test, Win7 has a high memory usage. After the article was published, it was reprinted by many media and caused the industry to debate the memory share of Win. However, the situation suddenly showed unexpected changes. After verification, the content of this article is not true, just an advertisement. ; A Windows 7 memory footprint details survey is attached later in this article.

In the 19th report, Craig Barth, chief technology officer of Devil Mountain, a PC performance testing company, revealed that nearly 90% of Windows 7 computers have an average memory usage of 90%-95%, which is averaged. The memory is 3.3GB, so the Windows 7 system needs to use more virtual memory to handle the task, which is almost twice the number of XP.

Many users and media have said that their test results are very different from those of Devil Mountain. After verifying the identity of Craig Barth, another well-known media InfoWorld issued a statement stating that there is no Craig Barth alone. This is just the editor of the website, Randall C. Kennedy, who used it to cover up his relationship with Devil Mountain. .

Randall C. Kennedy is actually the founder of Devil Mountain. The news delivered to ComputerWorld is to promote his company. InfoWorld said it had no prior knowledge of the matter. In view of this serious fraud by Randall C. Kennedy, InfoWorld will no longer accept his author in the future.

Windows 7 Memory Usage Survey

Earlier this week, PC performance testing company Devil M Chief Technology Officer Craig Barthes It is revealed that nearly 90% of Windows 7 computers have an average memory usage of 90%-95% and an average memory consumption of 3.3GB. Therefore, Windows 7 systems need to use more virtual memory to handle tasks. This number is almost XP. double.

DevilMountain's test report has caused a lot of repercussions. The following is a summary of the contents of some readers' letters:

<; An excellent operating system does not idle too much memory A significant portion of the occupancy is used as a buffer, "remaining"; memory should not be used as a measure of system performance. ”

Another user reported that the results he tested were quite different from those of Devil. From XP to Windows 7, the memory usage (2GB) rate ranged from 38% to 52%, not as high as 95% as in the legend. .

Technology blogger Peter · Powell deliberately installed Devil's test tool XPnetPM and found that the resource usage problem that was not felt before was revealed through the tool chart.

Like Vista, the SuperFetch feature in Windows 7 is the main reason for its large memory usage, but Microsoft has modified it to limit the negative impact to a certain extent.

The so-called pre-reading technology, that is, before loading a program, pre-loading a part of the data required for the running of the program into the physical memory from the hard disk, so that the program can be started up faster.

It is important to emphasize here that Devil's report stated that "Free (free) memory in Windows 7 is too small", but in fact, the portion of the memory that is occupied is “ Available is the difference in the word that affects the user's understanding.
