Hi saint_sley,
#1
absolutely crucial: look into the arm eabi to build a new userspace
with. Why? The TS boards use soft floating point math, without using the
on-chip VFP Acceleration unit. The arm eabi has shown some fairly
incredible benchmark improvements for floating point. Just do a google
search / wikipedia search for more details. There are only a few people
on this list that actually use the arm eabi, and I am not one of them.
There is a debian filesystem and toolchain available if I'm not mistaken.
#2
(sort of a subset of #1) You will likely need to install a newer kernel
and come up with a different in order to take advantage of the arm eabi,
which is required if you'd like to build an eabi userspace.
#3
use FFTW (see http://www.fftw.org)
