It is also important to remember that many intermediate files are
written to disk by most unix compilers: The input to the assembler and
the object file input to the linker. Plus there is the reading of the
c link time library (which can be very big if you are linking
statically). Depending on your processor speed, I agree that most of
your time in compiling should be spent on I/O.

[There are certainly intermediate files, but their size should be roughly
a linear function of the size of the input. -John]
