Same with me here: large game, no observers, fast machine, server running 
on localhost; client takes forever to display the movements of all units. 
In the first part of the move they crawl, then suddenly they speed up. The 
machine takes 100% CPU. That's a lot. The server disconnects the client 
almost every turn due to ping timeouts. Restarting the client from scratch 
speeds things up, reconnecting from the existing client makes it worse. 
After a few turns the cycle restarts. Memory consumage rises as well. I'm 
using the GTK 2.0 client.

Any clues?
