-By default Jenkins do estimate load to avoid over-provisioning of cloud nodes.

+Jenkins avoids over-provisioning of cloud nodes by examining the current load
+and deciding when more nodes are needed. Enable "No delay provisioning" to
+create a new cloud node on Amazon EC2 as soon as the NodeProvisioner detects a
+need for more agents. This may cause Jenkins to create more cloud nodes than
+it needs to serve the current jobs. These nodes will be terminated if they
+remain idle longer than the "idle termination time" setting. EC2 currently
+bills instances by the second, so this option should not have a large impact
+on your AWS bill. It will make cloud nodes available much more quickly for
+jobs and should reduce delays.
