I've done 4 runs for each build using vec_ld and VEC_LD2, and logged the
results of the last 3 runs for each build.
The results are in the attachment. This time I added -an -threads 1 and
the fps went up for both builds. It seems VEC_LD2 is slightly faster.
I am not sure I've put -threads 1 in the right place on the command
line, and I don't know if it matters -- this is a single-core ppc G4.
Let me know if you would like me to try something else.
