How to limit RAM memory usage for compiled matlab executables?

I use Matlab 2022b and the corresponding MCR2022b
Even for the following min. example the RAM-memory usage after startup is about 300MB or above. After some time it reduces to a quite lower amount.
Min bspw:
File:
%simple example for memory alloc as executable
j=0;
for jj=1:1e8
j=j+1;
pause(10)
disp(j);
end
Code for console:
mcc('-m', 'my_simple_exe_code.m', '-d', pwd, '-o', 'my_simple_exe_code')
For my real code problem, the numbers of RAM-memory usage are as follows:
After startup as .exe: 400-600MB
After 3h of running of .exe: 30-70MB
Running code in Matlab: 30-70MB of additional RAM-usage.
I already tried to set some additional options for the compiler
opts = compiler.build.StandaloneApplicationOptions([file_name,'.m'],...
'ExecutableName',exe_name,...
'OutputDir' ,deploy_path,...
'SupportPackages',{'none'}...
);
compiler.build.standaloneApplication(opts);
But this does not change anything.
As far is i understood matlab runtime load a number of functions into the memory. After the process is running stable it checks which functions are required at all and reduces the number of loaded functions. Is there a possibility to check the required packages/functions earlier?
