[parsec-users] amount of vectorizing instruction

I have been trying to determine how many instructions of parsec packages can be in vectorizing categories (SSE, SSE2, MMx and simd) using vectorization flags and gcc 4.3.3. But, I surprizingly found most of the loops of codes are not vectorized. So only few packages, (such as x264, streamclster and fluidanimate) have considerable amout of vectoring instructions and for most of them this amount is less than 1% !
If any one has the same experience, please let me know whether these results are correct or I have done something wrong.
Thanks a lt,
