This causes slower processing in favour of other processes. <code>htcacheclean</code> will sleep from time to time so that (a) the disk IO will be delayed and (b) the kernel can schedule other processes in the meantime.</dd> <dt><code>-t</code></dt> <dd>Delete all empty directories. By default only cache files are removed, however with some configurations the large number of directories created may require attention. If your configuration requires a very large number of directories, to the point that inode or file allocation table exhaustion may become an issue, use of this option is advised.</dd> <dt><code>-p<var>path</var></code></dt> <dd>Specify <var>path</var> as the root directory of the disk cache.
