===[0.1] Optimize and run a benchmark program specifically designed to make use of <code>glibc</code>===
Any packages compiled for the beagleboards can be installed without optimization. So far, in the case of <code>cdot-beagleXM-0-3</code> packages are compiled without it. Without optimizations, software installed in a system can only run on sub-optimal performance. In order to make use of ARMv7 architecture features, editing the <code>CFLAGS</code> to use <code>arm</code> optimization options will let the compiler attempt to improve the performance and/or code size of the program; resulting in a more efficient/faster system.
The goal of this release is to run a benchmark software named [http://en.wikipedia.org/wiki/Dhrystone Dhrystone] on <code>cdot-beagleXM-0-3</code> and record the results. Three (3) runs are required: '''No optimization''', '''Optimized for armv5tel''', and '''Optimized for armv7'''. Dhrystone is chosen as the benchmark software mainly, to test the general system performance of <code>cdot-beagleXM-0-3</code> and to test how much performance gain can be expected from optimizing a program. Other reasons include:
