RES memory is either decreasing or remaining constant

I am monitoring the correct parent process. But the value under the RES column either remains unchanged during a file transfer or it decreases.

If there is no increase or a very minor variation in memory then you can proceed with 0 in the (INCREASE in memory usage benchmark).

What about the average memory taken during file transfer?

You can take average values of memory noted during multiple transfer
