A locally run rm is a bad idea on an isilon cluster. It is single threaded and will make use of only one node's power. If you want a faster method, you'd be better off with the TreeDelete job as it is multi-threaded and will use the entire cluster's compute strength to complete. – MaQleod Oct 12 '12 at 22:54
