    WRONG WRONG WRONG!!

    This article is based on a complete misunderstanding of how prefetch works. Contrary to popular opinion, prefetch does NOT preload applications at bootup. Application prefetching does not take place until application launch has been initiated. Unused or rarely used prefetch entries will have virtually no impact on performance in any way. In any event the prefetch folder is self cleaning after 128 entries. Manual deletion of these files will impair performance and has no benefits. This has been extensively tested.

    See my comments on this article for a description of how prefetch really works:
