Talk:Prefetcher

message: If you view the link that is currently cited in the "Incorrect tweaking of the prefetcher" section numberd 3 you can see the following text - 
"So, first off, it is a bad idea to periodically clean out that folder as some tech sites suggest.  For one thing, XP will just re-create that data anyways; secondly, it trims the files anyways if there's ever more than 128 of them so that it doesn't needlessly consume space.  So not only is deleting the directory totally unnecessary, but you're also putting a temporary dent in your PC's performance."
Can we remove the citation needed flag?  —Preceding unsigned comment added by Ciper (talk • contribs) 05:33, 14 November 2007 (UTC)
thread_title:  Citation already provided in "Incorrect tweaking of the prefetcher" section 

message: Being new to wiki-editing, I have no clue what I should do, but this article is either extremely confusing or in blatant disregard of fact. 
Disabling the prefetcher does in fact reduce OS boot times (kernel load time), but increases application load time. While I am unable to cite a source, anyone who has followed the steps (disabling in registry, deleting select/all files in the prefetch folder) will notice that their boot times will decrease. People disputing this often include the load time for explorer.exe (the Windows GUI shell) which is noticeably increased. After a fresh install, this benefit of disabling prefetching is not immediately recognizable, but as the computer ages, more and more applications are run. over time, this adds up and slows down Windows' boot if prefetch is enabled because not only does prefetch need to load more and more installed applications, but it will also load into memory applications that will only be used once (such as the setup executables). On top of this, uninstalling unused applications does NOT remove the prefetched file and the prefetcher will also load those. 
Especially with the performance of today's PCs, there really is no need for the Windows prefetcher as it currently operates.

thread_title:  Misinformation 

message: "A second myth is that the user should delete the prefetch folder contents to speed up the computer. If this is done, Windows will need to re-create all the prefetch files again, thereby slowing down Windows during boot and program starts until the prefetch files are created."
If the prefetch files have become horribly out of date, wouldn't this speed up the computer on the second and subsequent boots? Or does the Windows prefetcher keep the information up to date even with changes to the system? --Damian Yerrick (talk | stalk) 19:54, 9 October 2007 (UTC)

but it is not in the help.  It is not in the official writeup although someone said that the version of defrag in Windows Server 2008 R2 exposed it in the /? help for a short while.

I have no idea if this constitutes a citation (or perhaps would be useful as a citation), but I suspect not in either case.  How do you provide a citation for an undocumented flag?  The existence of the flag is obviously true, but is it more important to include and spread the knowledge or to provide a cite and remove unsupported material?  I believe that we should provide knowledge first (especially when it is easy to demonstrate that it is accurate, as it is here), but what do I know?
BTW, the langa.com newsletter link is broken.
