I did performance measurement and improvements as my job for many years.
Experience showed that the problems often (nearly always) occured where
they were _not_ expected.
So I would suggest to do some measurements first.
You can do this with GNAT very easy by running gprof.

If it is assured that really the arrays are the problem then this could
be a way, but there raises the danger of (C-like) "buffer overflows".
