For benchmarking any printf() will make results meaningless ( 2000 cycles or so per printf() ). You have to stop your compiler from optimizing things away. A good way usually is to XOR every output into an (unsigned long) integer, which you'll need to print at the very end (else the compiler kann kill that as well). 200M/sec already sounds quite good btw. At Warren: if you do not believe in publishing you still can go for arxive (which I recommend to do).
