Solution of a memory usage problem during huge file seeding


Fairon

Recommended Posts

Problem (for Windows Vista+ x64 and maybe x32):

During long seeding of huge files which sizes are larger than the size of installed system memory consuming of almost whole available memory occurs. Windows begins to drop a part of the memory into swap-file, thus system performance decreases a lot. After closing mutorrent and ALL other programs that use these files the memory gets free.

Solution (to developers):

I suppose that seeding files are opened with CreateFile() API and FILE_FLAG_RANDOM_ACCESS flag. In this article: http://support.microsoft.com/kb/2549369 the above problem is described and solution is found: FILE_FLAG_RANDOM_ACCESS flag should not be used.

I hope you fix this problem in the nearest release.
