Joe, <I don't see any pipeline flushes in the code> Every mispredicted branch results in a pipeline flush. A huge 'case' statement where the switch is based on a random number is guaranteed to have at least one mispredicted branch per pass-through, no matter what method the compiler comes up with. <since the time is far outweighed by the time it takes to load the case statement.> Not in this case. In Kap's program, the code executed between two successive pipeline flushes is pretty small. For the P4, more time is spent waiting for this code to make it through the pipeline than actually executing this code. Tenchusatsu
