+# Load
+
+The `load` parameter serves the function of regulating the number of concurrent processes permitted per app-instance. The maximum load for each app-instance is 100.
+
+Consider the following scenario:
+
+There are three events (irrespective of whether they are periodic or ad-hoc events).
+
+- Event A has a specified load of 40.
+- Event B has a specified load of 50.
+- Event C has a specified load of 20.
+
+At the start, when the server initiates the event queue, the load is 0. If Event A is triggered, the load becomes 40. The remaining load that the app-instance can handle is 60. Therefore, Event B can also be started, which brings the total load to 90. At this point, Event C must wait until either Event A or B is completed because the current load is already at 90. However, if your app is running on Cloud Foundry with more than one instance, another instance with available capacity would process Event C.
