It's hard to compare since our tests are a bit different so here's my 
results. At the time. I was trying this I was using a ROM3 IIgs with 
a 4mb memory card and a Rev D Ramfast with 1mb cache and a 240mb 
Quantum hard drive.

This was timing converting that 850k file from AW3 to AWGS at a few 
speeds.It was interesting comparing the results fron the RAMdisk and
hard drive I also timed a shift boot at a few speeds. The RAMdisk was 
from the IIgs memory card , not a slinky card. 
As things sped up there were diminishing returns. I didn't gain a 
whole lot going from 14.1 to 15mhz
