   1.  How many milliseconds do you expect your event handler to take?  For 
example, test this by running your node (?) code locally on 100 events.  Use a 
local function call as the harness.  In a running system, there will be other 
overheads but this baseline will let us know if the handler itself dominates or 
the OW harness itself.
   
   2.  How much memory does your event handler need?  This has a direct effect 
on how many can concurrently run at a time per invoker instance.
   
   3. Are the events all causing the same action to be invoked?  (If not, how 
many and what might the pattern be?)  This affects locality and reuse and lets 
us understand the container startup/teardown (or pause/resume) overheads.
