Hi,
    I'm using the AdaGIDE editor (version 7.45.2) together with the
GNAT AdaCore libre compiler (release 2010) on a Win XP machine. I
would like my codes to run as fast as possible and here is the content
of a typical gnat.ago file that I use. Please let me know what
improvements I can make in order for an Ada program to run in the
minimum amount of time. I understand that setting the release mode
makes a program bypass some checks and make it run faster.


-gnatVa -O3 -gnatn -funroll-loops -gnatf -gnato
