OK, I am not a programmer so maybe my idea is not possible or stupid.
As far as I understand how it works now is that the server connects the agent and asks the agent the data of an item. All off my servers have about 50 items, which connect every 30 seconds.
If you let the agent bundle the data and send all data at once, that would need less connections, less running agents and would make it possible to use compression (and with that offcourse less datatraffic).
