I recently published an article superficially comparing the 64-bit 64
Studio distro with the 32-bit JAD distro. Both are running on AMD64 CPUs
here (3200+ and 3800+), the JAD system is running on the faster of the
two. I didn't do a lot of scientific comparison, but Ardour's status
display was revealing, its performance was clearly superior on the
64-bit box. I also edited some video files with LiVES, again with much
better performance on 64 Studio. However, 32-bit JAD has much to
recommend it, so please don't take this comparison as meaningful beyond
certain bounds (and I think a 64-bit JAD is already in the works).
Obviously the memory handling capacity is much greater on the 64-bit
machine, and I expect that we'll all be running 64-bit boxes eventually.
