These graphs show how long it takes to deliver the observation events generated 
from 1000 added nodes. The vertical axis shows the number of pending events at 
a given time. The horizontal axis shows the time elapsed in milliseconds. 

In "1 transaction" all nodes are persisted with a single save call whereas in 
"10 transaction" the nodes are persisted with a total of 10 intermediate save 
calls. 


                
> Generating observation events takes too long when intermediate save calls are 
> involved

> Creating observation events is much more expensive when a transaction is 
> broken down through intermediate save calls compared to only having a single 
> save call.
