73% is not very full. The knee of the curve for performance fall-off of a full disk usually occurs above 85%. I wouldn't do anything. What type of file system? YOu can see this with the df -T option. The find command calls stat(2) on every file. Performance is strongly dependent upon the number of files and not the size of the file nor the amount of free space. If your system is gathering up a lot of little files then find will take longer to stat(2) each of those files. Strongly affecting system performance will be the amount of ram available to provide file system buffer cache for the file system. The tool I like the best to look at general system memory use is 'htop'. Look at the "Mem" bar graph. http://hisham.hm/htop/index.php?page=screenshots If you are suffering what seems like slow disk performance the problem may be lack of sufficient ram to provide sufficient file system buffer cache.
