Can you say "I/O Bandwidth"? I knew you could.... :-)
Seriously, I/O bandwidth is what separates mainframes from workstations
from minis. Compilation is I/O intensive, particularly if your compiler
drives your 3100 into heavy swapping or paging. Retime those compilation
tests and look at system times vs. wall clock time. I think you'll see
some telling numbers.
