PC slow after playing a movie |
|
|
A movie is approx 700MB in size (divx and xvid) or sometimes even 1.4GB.
System memory is 512MB (448MB effectively, due to shared video memory).
When a movie is finished playing, the MCE box is hooribly slow, the harddisk
goes berserk for the littlest things. This indicates the Windows file cache
has kicked in, and has tried to cache the 700MB movie file.
This should *never* happen. It's completely useless to try and cache such a
large file (or any movie file) in system memory. It only slows down a PC and
it's never an advantage.
My suggestion to the MCE developers: open movie files with the
FILE_FLAG_NO_BUFFERING flag. That should prevent caching. Some file manager
programs (like Total Commander) already use that flag to copy very large
files - another situation where the file cache is completely useless.
