Do you know any tools that can measure this?
I am not sure that this program is the cause of your slow response time. There is a tool that you can use to examine these IP datagrams and examine the size of each packet. It's called an Analyzer. A couple of common analyzers include Sniffer and Etherpeek; both are good choices, but are expensive! I would suggest you download Ethereal; it's free and will provide you with the information you are seeking. Best of luck!
