You can check my web site, I've a VM patch for 2.6 (NOT 2.7) to control the
amount of times squeak copies the updated squeak virtual screen to the
actual OS window. This  might improve things since you reduced the amount of
interaction with your graphics card. You will need to build a Window's VM
since I've only an example Mac VM with the patch applied.


PS I've been working with Andreas on getting the PowerPC and 68K version
faster, 10X?, well anything is possible....
