To follow up on the last comment. It seems that the profiling stats show that the slowness is not processing the query, but is somehow related to moving the data around after its found.  I'm not sure if the changes to inter-node communication between ES 1.7.4 and 5.4 would have any impact.   We are using AWS i3.xl nodes - so the network between them is pretty good.
