In particular, if there is not active DNS server, you can get long DNS timeouts 
on attempts to reverse lookup (PTR record query) from ip address to get names.

There is also the download of the servers codebase jar files in the mix as well.

There are TCP traffic monitoring tools available that you can run on the client 
and the server to see what types of network traffic are flowing and how long 
delays are.
