The only idea coming to my mind is replacing cc1.exe by a link
to the version on your ramdisk, or, more elaborate, a tiny program
that checks if an cc1.exe exists on a RAMDRIVE, and execs that,
otherwise execs cc1org.exe in your djgpp directory. I'm not sure 
if this really works, but ypu might try. 

On the NW side you might try 
 - increase the number of PB Buffers
 - increase the number of PBurts Read Window
although I didn't notice an overwhelming effect.
