Game processing getting sluggish since maintenance on Sept 15

[R292606021]

Sorry for bad English. Not sure whether this post is suitable in which session.
The game is terribly slow and no longer smooth like before. I've to reload the page very often even in small dungeon. This is getting serious from time to time. By the way, I'm having trouble login through facebook with miniclient too.

Any caused and solution for this? Your helps is greatly appreciated.
