	I think you'll find caching the most beneficial with a caching HD 
controller such as RamFAST.  The board can recognize a cache hit and DMA 
requested information to the GS's memory faster than the GS can move 
information around main memory if you were to rely on GS/OS for caching.  
With a 1MB RamFAST in a ProDOS 8 environment I suspect you could cache 
the entire ProDOS operating system and a decent sized application (handy 
since many P8 programs are segmented into tiny files for use on low 
memory systems.)  I think this Naprosyn is helping my cold symptoms too.
Also, let's try not to pick on posters for whom English is a second 
language.
