We have a web page that loads slow for everyone on every computer. It has a 20 or 30 second delay to load. The webserver is a very robust server so I am thinking that it is probably some other server that sends data to the webserver.
I have looked at the flow graph and the server and client both stop talking to each other for 20 seconds while the server waits for something.
What would be the best use of Wireshark in this situation?
Do I need a different tool than Wireshark?
