What region are you located in? It sounds like there's quite the delay in getting you the data to begin with. You could try forcing off-line mode in options and seeing if that makes any improvement for you. Offline mode requires you enter your player ID and faction to start session and will never show you enemy information, but it could help identify the issue or at least make it more usable.

The PS2 game server sends the data to their websocket server, their websocket server sends the data to you, if you don't have enemy information (like name) then it queries the census server for the data. The time adds up. Offline mode removes the last query.
