------------------------------------------------------------
I have submitted a bug fix for the perf degradation
There are 3 places where the optimizations are done
# Writing out responses
# Indexing
# deserializing responses during inter-node communications
The changes are minimal for #1 and #2 and #3 are complex
I would recommend reverting #2 and #3 and let #1 continue to be there with the
bug fix (and more auditing) I have just submitted.
I'll go with the decision of the community and do the necessary work
