The scenario is as below, we have a cluster environment with 7 nodes

If request lands on the server the user is logged into, the response happens within a 1 or 2 seconds

But if it lands on any of the other nodes, we see a 5 second delay, this delay is caused by a remote ejb call to the node the user is on. We are seeing this same 5 second delay, even if
there are 2 nodes, and the request lands on the other node.

Please suggest me is there any way to reduce this lag, Thanks in advance
