Changes

The benchmark graph shows that optimization increased the overall performance of cdot-beagleXM-0-3 by '''36%'''(Normal run vs. Optimized for armv5tel/armv7). The results for both armv5tel and armv7 optimizations are the same. (It can be assumed that the armv5tel glibc impacts the performance of C library dependent programs such as Dhrystone). Another possible reason is that the compiler used is already armv7 optimized (since dhrystone also relies on the compiler efficiency) The data gathered can be used as a reference for conducting 0.2 project release.
