It depends on what exactly is loaded at boot time (TSRs, device drivers) 
and what kind of jobs do you do most.  In general, I don't recommend 
putting the compiler into the RAM disk, since the .exe are large and will 
quickly exhaust the RAM drive.  Let the disk cache handle these.  TMPDIR 
should be the first candidate for the RAM disk, then the headers (if you 
compile a lot).

But having only 8MB means that you need to experiment and time your
real-life jobs to see which setup is best for you.  I don't think anybody
can give you a reliable advice based on hearsay.  That's why the FAQ
avoids saying anything specific for this borderline case (although I
myself had an 8MB machine for several years).
