True, and it will be interesting to see if this makes any relative difference between 2.3 and 2.4. The important thing though is that the same compilation options were used for 2.3 and 2.4, so I'm comparing like with like.
BTW, other comments have indicated that -Os might give the best results (can fit more in cache).
