Memory occupation

[CyGa]

Hello,

I've made a program to send strings on a RS232 port. The VIs which are part of this program are quite small. Nevertheless, when I launch this program it occupies 20Mo of RAM. I'm using strings arrays but they are quite small and it doesn't justify this amount of occupied memory.

Can somebody tell me why it uses so much memory?

Thanks!

Look at File>>VI Properties and select "Memory Usage".
That way you can see that it is not your VI that allocates the memory.

I assume that you see in Task Manager that your application consumes about 20MB of memory.
It is the LabVIEW RunTime that alloctes the major part of it.
You can verify this by creating an application that runs an empty VI (= do nothing.VI).
Even this application allocates on my computer about 20MB of RAM.

Thank you very much Guenter!!
I was far away to think that LabVIEW's runtime was taking so much memory!!

Same with me.
