I have a an java application accessed by huge number of applet based clients over proprietary http based protocol. Clients access a central server through various levels of proxies. A group of clients clients and last level proxy are in the same Lan (same institution's branch). Server is connected to legacy backend.
Application suffers a latency, response time problem. I think it is in part due to not that much efficient, web-service like, request based protocol. Is there any way to make this more efficient, maybe pool these connections in some way?
Distributing application is at the moment out of question.
