Hi everybody,

I am playing around with Ada95 since nearly two weeks
for an upcoming project, trying to select the best
language for a headless server application. I am using
CodeBuilder from Feldman's Ada book which comes with
gnat and gnu c. My experience while compiling and running
the dhrystone benchmark was that the C version of the
Dhrystone was nearly twice as fast as the Ada version, and
this sounds really bad. Has anyone any idea why this
is so and how to solve this problem. What I was expecting,
because gnat isn't a compiler env. but a to-C(++) translator,
the performance decrease about ten to twenty percent but
not 50 percent.

Harald
