This looks normal to me. On McKinley, a "single-cycle loop" usually take a bit more than a cycle to execute on average. If we assume that 4 iterations execute in 3 cycles and consider that BogoMIPS counts each iteration as 2 instructions (decrement & branch), you'd expect to see 2*900e6/(4/3)=1350, which is close to what see. Of course, you could unroll the loop, but there is a reason it's called _Bogo_MIPS... ;-) --davidReceived on Mon Jun 02 12:17:15 2003
