Yes cache may bias the results somewhat, though /dev/urandom is surprisingly slow: $ dd bs=1M count=100 if=/dev/urandom of=/dev/null 100+0 records in 100+0 records out 104857600 bytes (105 MB) copied, 23.3218 seconds, 4.5 MB/s _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
