Sure, but I still think it's difficult to compare systems. Processors 
just weren't that fast back then. You could have 256 of them, and lots 
of RAM, but the RAM architecture was slower too.

If your compiler could run in parallel to build, perhaps you could get 
faster compile times, but it's so difficult to compare these things in 
an apples-to-apples comparison. Especially when the size/complexity of 
the program being compiled isn't necessarily analogous.
