Available Distributions What is armhf The official Debian Squeeze image issued by the Raspberry Pi foundation uses "soft float" settings. The foundation found it necessary to use the existing Debian port for less capable ARM devices due to time and resource constraints during development of the Raspberry Pi. Therefore, it does not make use of the Pi's processor's floating point hardware - reducing the Pi's performance during floating point intensive applications - or the advanced instructions of the ARMv6 CPU. The official Raspberry Pi distributions (http://www.raspberrypi.org/downloads) are now optimized for ARMV6 and for "hard float" which should have better performance on certain CPU intensive tasks. There are some info on the news groups that "hard float" optimization can speed up floating point operating up to 10x, please read detailed discussion on Raspberry Pi forums - http://www.raspberrypi.org/phpBB3/viewtopic.php?p=61497#p61497
