Basically, see if a straight-up pipe will buffer reasonably. If not, I suppose it's remotely possible that this is just a CPU-bound operation and it can't keep up. I can't imagine that's really the case though with that CPU.
Libvorbis uses floating point operations while on your AT91SAM9261 you have a soft-float library (or even worse FPU emulation).
Try the integer only Tremor library linked here: http://www.xiph.org/vorbis/
The API is slightly different (easier), as it can only generate S16_LE samples.
