Adding another cache_dir directive will not help (unless it's on another spindle/drive). For what it's worth, the "single directory" is a single parent directory. The additional arguments to cache_dir specify how many sub directories to use (in your case, 16 sub-directories with 256 sub-sub-directories each, or 4096 directories in total, not including the parent). For 100MB of content, that's plenty. Chris
