The other thing to point out is that the Ada compiler does something.

It doesn't just cram bytes into a binary file.
It checks to see if the bytes are edible first.

Starting with nothing compiled, on a project with over 17,000 source files
(million-plus SLOC) ....

On a Sun SPARCserver-1000, with one processor, and source files NFS
mounted, and a fairly heavy load from other users (it's one of our main
fileservers) .....

I ran a script that does gnatmake with optimization for 98 executables.

Took about ten hours.  Takes _MUCH_ less (but I don't have exact numbers) on
a four-processor Ultra-2 with source on local disks.

Apex speed on the same source is slower but comparable.
