Standard (-O) optimisation, Release 3.5 SUN3 and Release 3.2-Sys4-R2 SUN4.

(I used 100 and divided by 10 to get the above results). -- | Adrian Cockcroft anc@camcon.uucp ..!uunet!mcvax!ukc!camcon!anc -[T]- Cambridge Consultants Ltd, Science Park, Cambridge CB4 4DW, | England, UK (0223) 358855 (You are in a maze of twisty little C004's, all alike...)
