Final Fantasy XI Interview with Yoji Fujito and Akihiko Matsui
Has your development team discovered any ways to reduce server lag and congestion during high-population events, such as Dynamis Divergence zones?
Akihiko Matsui: At the moment, it's very difficult for us to make any more adjustments in that direction. We unfortunately cannot remedy issues with model rendering unless we were to adjust config settings.
Yoji Fujito: There will always be some amount of lag when it comes to content with a large number of players. We try to design new content (not updated or revamped content) to minimize lag-related issues, As the underlying systems are all premised on PS2 specifications, it isn't feasible for us to make adjustments to those systems (for example, revising the model rendering system itself or changing the way data its sent to and received from the server.)"
