[PD] Raspberry Pi versus BeagleBoard ?

Wow! Are you using their satellite distro ? What version of the beagleboard
are you using ? 72 ms is definitely unusable for realtime effects.
I can't seem to find any info about the latency they achieve and this is a
bit strange. A low latency is a sine qua non condition if one wants to
build a stompbox.
