→[0.2] Install an armv7 glibc and re-run the benchmark using dhrystone
The Dhrystone (DMIPS) results never changed. The benchmark brought the same, exact number of DMIPS. Although Dhrystone does make use of C library functions and is assumed that the glibc would have effects on the program; the results proved that upgrading the glibc did not bring what's expected.
It is proven that armv7 and armv5 provide the same level of performance especially when running C library dependent programson cdot-beagleXM-0-3 builder. Why is it possible when armv7 architecture is supposed to be faster better than armv5tel? One big hint to the question answer is that the armv7 system tested currently is built to use an [http://en.wikipedia.org/wiki/Application_binary_interface ABI] called "softfp". Although beagleboardXM (cortex-a8)supports the "hard floating-point" ABI, The Fedora-ARM currently can't afford to waste time in recompiling the packages to support "hardfp".
