Eric Evans commented on CASSANDRA-1765:
---------------------------------------

So I went ahead and applied some of the remaining feedback from Scott Carey and the results where very impressive.

https://gist.github.com/6be358038fce183911b5

Most of this came from the reuse of the Encoder (and backing outputstream), and Decoder.  I'm not  entirely sure whether the datum reuse is valid, or representative of Real World use (I think it is), but that contributed to less than 100ms toward the deserialization improvements.
