Finding maximum of an array

I am trying to optimize a procedure that tries to locate the maximum value
in an array of single. I am working with huge arrays, so this is the
bottleneck of my program.

for J := N to M do
if (ARow[j] >= RX) then begin
L := J;
RX := ARow^[j];
end;

Is there any Fastcode function that would allow me reduce the speed of such
a procedure or is there any existing RTL function that would help me.
