Hey Kevin,
Do you think that maybe looking into somehow optimising the resultant
assembler code from the plex86 codebase would help speed up the final
virtualization code? I know that you make your actual assembly work as fast
as possible, but could we get any observable gains from optimising the C/C++
portions of this project in a more "hands-on" way?
