I find this hard to believe, unless your system has awfully non-optimal
configuration.  A typical compile, even on small modules should dwell in
CC1 much longer than in CPP and AS.  I suggest you check your
configuration (especially how much free DPMI memory does Windows let you
use) as per section 3.9 of the FAQ.

With a large cache and TMPDIT that points to a RAM drive, most of the I/O
to temporary files actually boils down to memory moves, and those are
lightning fast on a Pentium.

Did you actually check this?  I did, and on many workstations there is no 
visible difference.  The reason, again, is that Unix has a well-tuned 
disk cache.
