Is there any way to solve the issue: receive events delay?

In our Cloud Service project, we have 2 instances for work role (deploy to Azure), the work role is consume events from the EventHub using EventProcessorHost(host name is RoleInstance name).

We send 100 events (event1~event100 by order, each seconds send 1 message) to the EventHub, but we receive the message is not ordered, like (message 25, 6, 26, 27, 8), after a while, the receiver become stable. We will receive events by order,

So we have the events delay issue:

like we send Event6 at 15:35:12, but we receive the Event6 in 15:35:31, so it not the real live data for Event6, so is there any way to solve the issue?
