Well, let me compare this to our VAX 11/750 running 4.2BSD. The disk we use is RA81: Script started on Wed Jul 22 22:24:23 1987 103 $ time cat /usr/dict/words > /dev/null real 0m31.53s user 0m4.61s sys 0m2.26s 104 $ ^D script done on Wed Jul 22 22:25:01 1987 The system at the moment has 5 users and the load is 4.2.
