Eric,

Since I have the same machine, here are some comparison numbers (all in morphic):

2.8 with 2.8.3 VM - '39653035 bytecodes/sec; 1261621 sends/sec'
3.1 with 3.0.a2 VM - '37426900 bytecodes/sec; 1138220 sends/sec' (higherPerformance ON)
3.1 with 3.0.a2 VM - '34538586 bytecodes/sec; 1047908 sends/sec' (higherPerformance OFF)

So, while 2.8 is faster, my numbers are a little closer together. Some things to consider:
- the MacOS is not exactly the spiffiest multiprocessing OS you could imagine. Were any other apps running at the time?
- Try turning ON the preference #higherPerformance. This tweaks things a bit for maximum foreground performance when in Morphic. Do not use this option when in MVC.

Cheers,
Bob
