Dear xdg list, Over at GNOME land we have the problem that due to the huge size of the thumbnail directories, refreshing in-memory thumbnail readdir() caches takes very long.
The caches are required as thumbnails are looked up for *every* file one opens with the file manager, so the cumulative performance impact is significant. http://blogs.gnome.org/cneumair/2007/04/29/thumbnail-followup/ http://blogs.gnome.org/cneumair/2007/08/29/thumbnail-followup-2/ Alexander Larsson proposed to reduce this delay massively by using nested directories - git does that as well: The first two digits of the MD5 hash "4f831f...89" would be split apart, and used to create a subdirectory "4f". The thumbnail file corresponding to the specified example in this directory would then be named "831f...89.png". So the entire hash maps to the file "4f/831f...98.png" rather than "4f831f...98.png" This definitly allows better cache-refreshing. For backwards-compatibility, it may be a good idea to store this in a new location, maybe ~/.thumbnails/hashed-failed and ~/.thumbnails/hashed-normal rather than ~/.thumbnails/normal and ~/.thumbnails/failed. -- Christian Neumair <[EMAIL PROTECTED]> _______________________________________________ xdg mailing list xdg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xdg
