    I have run some more tests looking at modifying the parallelism of 
different components.
    
    First I kept the parallelism of everything else at 4 and modified the acker 
count.

    I also kept the ackers at 2 spout and count at 4 and modified the splitter 
count

    The acker drop off at 5 is really scary,  but adding too many splitters 
also shows a lot of problems.  I am going to try something similar without the 
patch for comparison.
    
    Overall the numbers look really good in some situations, but it is really 
easy to slip into much worse territory.  @knusbaum said that he was able to get 
a multi-worker setup to work, so that is something else I want to explore.
