Hi Andrea,
I started the operating system and then I launched my application. Then I could see by difference something like 46 MB of RAM just related to the newly launched application.
Some time ago I found a tool which is much better/detailed then the standard Windows Task Manager. You can get it from www.sysinternals.com (which is now a MS subsidery or something like this). Their Process Exlorer gives more detail on the memory usage and you can also open a panel for the process which then shows dependencies (i.e. which .pyd and dll are used by the process).
It might help to at least identify what uses how much.
