Hopefully this will give some idea of the relative speeds with and without the booster and blitter.

Just for completeness I ran Gembench on my stock STE with 4MB RAM and TOS 2.06, and saved the results. I then ran Gembench with those defaults on my 32mhz boosted STE. RAM and TOS were the same.

Results below, with and without Blitter.

Without Blitter:

Oddly running the CPU from its own 32MHz oscillator gives integer division a 16% boost in speed :shrug:
