I tested two packages.

One compares a number (6-8) byte move subroutines (memcpy, bcopy, a variety
of Duff's devices (using char, short, and int), and some other "fast" byte
copies I've snarfed over the years).

I run a reasonable quantity of different size/alignments against each of 
these, and report the CPU time of each one.

The second test is much less (?) useful: I compiled my Mumps implementation
with each compiler, and ran 11 coarse-grained tests (for loops, subroutine
calls, (string) arithmetic (integer and real number), symbol table stuff, a
variety of string operations (catenation, justification, formatting),
pattern matching, database ops, and probably a couple of others.  I run 
this test on a "quiet" system, as the test uses wall-clock timing (but each 
test runs for 30-60 seconds, on average).

If I could get TenDRA to produce an executable that can be run under 
gprof, I'd do that instead.
