If I have two sites from where I connect to a separate server in a remote location. From 1 site I can connect fine, i.e. good response times etc. However from the other site I cannot connect and the application I am connecting to is extremely slow.
My question is, how does one go about finding the exact hop/location where the issue is being caused?
Traceroute from both sites in both directions is showing no packet loss, and same response times however 1 site is still slower in loading on the client side. The client is a GUI which basically sends xmlhttp requests to the server. 1 site is fine and loading times in the client are good - however the other site the loading times are very slow and I get disconnected from the server a lot.
There are 3 seperate ISP's involved here. 1 network is where the server is hosted. 1 client, and the other client (the slow one). Nothing has changed from my side, i.e. I have not configured anything differently and the slowness seems to be completely random. Plus I have no visibility of how the ISP is balancing/routing etc.
