Client frozen on transfer packet

After sending the client a transfer packet the client freezes for ~2 seconds before even a loading screen is displayed. Is there any way to a) shorten this sequence, and/or b) display the loading screen as soon as the request is made.

Right now you can have it so you click an NPC to load a game server, then your client freezes, then you begin the sequence to connect. On mini game networks you really want a rapid flow. Even just the building terrain screen is a drag.
